When seven skeletons are unearthed along the Appalachian Trail, FBI Special Agent Margot Phalen thinks she already knows who put them there.

Margot knows how predators hunt. As the daughter of one of America’s most notorious serial killers, she’s turned her dark past into a weapon, becoming the Bureau’s expert at getting inside the minds of monsters.

Wyatt Holmes has been behind bars for a decade, convicted of hunting hikers like animals through the Tennessee wilderness. He claims wolves led him to his prey. Everyone thinks he’s insane and surely responsible for the newly discovered skeletons—until the bodies start telling a different story. The burial patterns are wrong. The timeline doesn’t fit.

And as Margot ventures deeper into the wilderness where Holmes once stalked hikers, she discovers a horrifying truth: someone else is out there.

This time, she isn’t the only one hunting—in fact, she’s become the target.

A heart-pounding thriller that will leave you breathless. Perfect for fans of Lisa Gardner, Karin Slaughter and Gregg Olsen.

I really enjoyed this book. It’s a psychological thriller that slowly builds tension and keeps you interested throughout.



The story follows a woman whose life is disrupted when unsettling events begin to unfold around her, including the discovery of bodies that deepen the sense of danger and mystery. As things escalate, she is forced to question who she can trust and what is really going on, with the feeling of threat growing stronger as the story progresses.



Kate Wiley’s writing is easy to read but still creates a strong atmosphere. She does a good job of pulling you into the characters’ experiences without overcomplicating things, which makes the story feel very readable and engaging.



The plot unfolds at a steady pace, revealing just enough at the right moments to keep you guessing. It kept me wanting to know what would happen next.



What I enjoyed most was the tension and pacing. It holds your attention without feeling rushed, and the suspense is consistent all the way through.



Overall, a solid and enjoyable thriller that kept me engaged and entertained.



Thank you to NetGalley, Storm Publishers, and author Kate Wiley for this ARC in exchange for my honest review.

With so much uncertainty in the world at the moment, I stuffed my week with feel-good, predictable, sweet romance novels. When my brain was comforted, and I needed something more…maybe from a sense of trying to understand the chaos, I knew a good psychological thriller should be next on my reading list. This release couldn’t have come at a better time for me. Thankfully, book one was on Kindle Unlimited, so I was able to get familiar with Special Agent Margot Phalen and her background before reading the sequel. This safe way to learn about threats was a welcome read.

I liked getting closure on the accusations presented in book one so that I could focus on the new challenge facing SA Margot. I also appreciated the author giving us more background on the Classified Killer. The pacing was perfect, and the questioning and clue following kept me flipping pages. It was good to see how Margot mentally approached the crime scene, eliminating and collaborating before she came to a working hypothesis. My mind needed this workout. I like how this author writes and I’ll be searching out more of her books.

Margot is a great heroine; she faces the evil and puts in the effort to understand it and overcome the fear.

If you are new to this series, start with book one. It's worth it (super creepy), and it’ll give you the background you need to understand Wes Fox’s case and SA Margot Phalen’s drive. That being said, this book could stand alone if reading time is a factor.

I’m excited to have a new series to follow.

I was gifted this copy and was under no obligation to provide a review.

As the daughter of one of America's most notorious serial killers, Margo knows how predators hunt. She's turned her dark past into a weapon, becoming the FBI's expert at getting inside the minds of monsters. The wilderness setting, where 7 skeletons along the Appalachian Trail have been unearthed, added to the eeriness. There's lots of suspense as the story follows FBI Special Agent Margot Phalen's investigation.

I liked The Wolf at the Door a lot! Although I have not read the first book in the series, I didn't feel lost as I read this one, and in my opinion, this book can be read as a standalone. For the most part, I was impressed by Margot's investigating skills. (I must say, though, if she doesn't marry Wes, I will, haha!) I'm officially ready for book #3!

3.5 rounded up for GR

I don’t think this one was necessary this soon after book one.

It almost felt like a repeat of book 1. The same structure, same pacing, just a different case, location, and characters. We get a crime, Margot steps in, works the angles, and everything unfolds in a very familiar way. I found myself feeling like I had just read this story, just told slightly differently.

That said, I’m still invested.

I’m attached to Margot at this point, and the action and pacing are strong enough to keep the pages turning. Even though I figured out who the killer was pretty early on, the full reveal and details at the end did pull it back up for me.

I just wish there was more progression from book one, something that made this feel like a true continuation instead of a copy and paste formula.

Overall, a solid read, just not as original or impactful as I was hoping.

First of all a big thanks to NetGalley for sending me this ARC to read in exchange for my honest review.

I really enjoyed this book. My first book by this author. I realised it was book #2 in the series & I’d not read the first book but honestly it made no difference, I couldn’t tell or I didn’t feel I’d missed out on anything. I loved the main character Margot & it was great following all the twists & turns & I could really imagine myself in the scenes that were described. There was a serial killer on the loose but the bodies had been discovered in a clearing on a hiking trail which raised a lot of questions. The story was told/written well & kept me interested. I had an inkling but didn’t really guess the outcome & the ending easily indicates there will be a 3rd book! Highly recommend this fast paced read by this great writer 🤩

Kate Wiley’s *The Wolf at the Door* is a gripping and atmospheric thriller that blends psychological tension with a wilderness survival narrative. With its intriguing premise and a protagonist shaped by a dark and complex past, the novel promises a chilling exploration of predation, both human and symbolic. While it delivers plenty of suspense and engaging moments, it does not always fully capitalize on its potential, resulting in a strong but slightly uneven read that earns a 3.5 star rating.

At the center of the story is FBI Special Agent Margot Phalen, a character whose backstory immediately sets her apart. As the daughter of one of America’s most notorious serial killers, Margot has built her career on understanding the psychology of predators. This personal connection to violence adds a compelling layer to her character, giving her both an edge in her work and a vulnerability that surfaces throughout the novel. Margot’s perspective is one of the book’s greatest strengths, as her internal conflict between control and inherited darkness adds depth to an otherwise familiar investigative framework.

The plot begins with the discovery of seven skeletons along the Appalachian Trail, a detail that immediately establishes a chilling tone. Margot initially believes the remains are connected to Wyatt Holmes, a convicted killer who has been imprisoned for a decade. Holmes is a fascinating figure in his own right, with his claims that wolves guided him to his victims adding an eerie, almost mythic quality to the narrative. However, as inconsistencies in the evidence begin to emerge, the story shifts into more unpredictable territory, raising the possibility that another predator is at work.

The wilderness setting is one of the novel’s most effective elements. The Appalachian landscape is depicted as both beautiful and menacing, a place where isolation heightens danger and survival becomes uncertain. Wiley uses this environment to amplify the tension, creating a sense of unease that permeates the story. The forest is not just a backdrop but an active presence, reinforcing the theme of hunting and being hunted. This atmosphere works particularly well in the latter half of the book, where the stakes become more immediate and personal.

Despite its strengths, the novel does have some pacing issues. The opening sections are strong, quickly drawing the reader into the mystery, but the middle portion can feel somewhat drawn out. Certain investigative threads are repeated or linger longer than necessary, which slows the momentum of the story. While these moments do contribute to character development and thematic exploration, they can disrupt the otherwise taut pacing expected of a thriller.

Character development is another mixed aspect of the book. Margot is well realized, with her internal struggles and professional determination making her a compelling lead. However, some of the supporting characters feel less fully developed. Wyatt Holmes, for example, is intriguing but not explored as deeply as he could have been. His motivations and psychological complexity are hinted at rather than fully unpacked, which leaves parts of his character feeling underutilized. Similarly, other secondary figures serve their roles in advancing the plot but lack the depth needed to make them truly memorable.

The novel’s psychological elements are engaging, particularly in how they explore the nature of predation and the thin line between hunter and hunted. Margot’s ability to think like a killer adds an interesting dimension to the investigation, and the story raises questions about whether such insight comes at a personal cost. These themes are compelling, though at times they could have been pushed further to create a more profound emotional impact.

One of the more intriguing aspects of the book is its flirtation with ambiguity, particularly in relation to the idea of wolves as both literal and symbolic guides. This element adds a layer of unease and mystique, though it is not always fully developed. Some readers may find this ambiguity compelling, while others may feel that it leaves certain questions insufficiently answered.

The climax of the novel is tense and satisfying, delivering the kind of high stakes confrontation that the story builds toward. Wiley effectively raises the tension in these final sections, placing Margot in immediate danger and forcing her to confront both external threats and her own fears. While the resolution ties up the main plot threads, it does so in a way that feels somewhat predictable, preventing the ending from reaching the same level of impact as the novel’s strongest moments.

Overall, *The Wolf at the Door* is an engaging thriller that combines a compelling protagonist, an atmospheric setting, and a solid central mystery. It excels in creating tension and exploring the psychology of its main character, even if it occasionally falters in pacing and character depth. The novel offers enough suspense and intrigue to keep readers invested, while also hinting at deeper themes that could have been more fully explored.

For readers who enjoy dark, character driven thrillers set against evocative natural landscapes, this book is well worth picking up. While it does not fully achieve the intensity or originality it sometimes promises, it remains an entertaining and thoughtfully constructed story. With its mix of suspense, psychological insight, and atmospheric writing, *The Wolf at the Door* earns a respectable 3.5 star rating.

The Wolf at the Door by Kate Wiley

Synopsis /

When seven skeletons are unearthed along the Appalachian Trail, FBI Special Agent Margot Phalen thinks she already knows who put them there.

Margot knows how predators hunt. As the daughter of one of America’s most notorious serial killers, she’s turned her dark past into a weapon, becoming the Bureau’s expert at getting inside the minds of monsters.

Wyatt Holmes has been behind bars for a decade, convicted of hunting hikers like animals through the Tennessee wilderness. He claims wolves led him to his prey. Everyone thinks he’s insane and surely responsible for the newly discovered skeletons—until the bodies start telling a different story. The burial patterns are wrong. The timeline doesn’t fit.

And as Margot ventures deeper into the wilderness where Holmes once stalked hikers, she discovers a horrifying truth: someone else is out there.

This time, she isn’t the only one hunting—in fact, she’s become the target.


My Thoughts /

First and foremost, a huge THANK YOU to NetGalley, Storm Publishing and author, Kate Wiley for providing me with a copy of this publication, which allows me to provide you with an unbiased review.

When Easter rolls around in Australia and you get a whole four days off work. It's school holidays, the roads are packed with eager travellers, supermarkets are jammed with everyone trying to purchase last minute groceries for their trip away, and fathers' making that last minute dash to buy Easter eggs for their children (the ones that their wives/girlfriends/significant others had reminded them to buy days earlier). Ah, good times. But beyond religious reflection and a break from work stress, Easter is my annual sanctuary for hours of uninterrupted reading. – something that I don't always manage to achieve in my day-to-day life. And what better way to spend some reading time than to crack open the second instalment in the Margot Phalen FBI Series by Kate Wiley.

I’ve loved every single book I've read by this author. Honestly—and I say this knowing I'm testing my luck—I’ve been half-expecting a dud by now. But I really don’t think that’s going to happen, and here’s why:

🥇Wiley has proven time and time again that her character development is nothing short of masterful. She excels at crafting realistic, multidimensional characters who evolve through deep motivations, rich backstories, and gripping external conflicts. Through evocative details and a razor-sharp style, Wiley breathes life into every scene, pulling the audience into the lived experience of her characters.

🥇Her style of writing is essentially the literary equivalent of a high-speed chase. It works because it prioritises momentum and visceral reactions over flowery prose; using short, punchy sentences and ending off chapters on little cliffhangers; creating a 'just one more page' loop that makes the book impossible to put down.

This series centres on FBI Special Agent Margot Phalen, who uses her unique perspective as the daughter of a notorious serial killer to hunt predators. Margot and her team usually work cold cases but in The Wolf at the Door, author Kate Wiley has changed things up a little differently for Margot – and in this story the team is chasing a killer who is very much alive.

Wiley uses setting to her advantage and in this instalment, it's the Appalachian Trail. Established in 1937, the A.T. is the world's longest hiking-only trail, traversing 14 states, diverse ecosystems, and spanning protected lands. Making it the perfect dumping ground for a serial killer.

What seems initially straightforward quickly becomes anything but, with links to past crimes and the involvement of a second serial killer adding an extra layer of tension and uncertainty.

With thanks to NetGalley and especially to one of my favourite publishers, Storm Publishing 💗 for the much appreciated arc in return for an honest review. All opinions expressed in this review are my own. The publication date is currently set for May 19, 2026.

4.75* I stood Eve Dallas up for Margot Phalen, and have no regrets.

Book 2 in the new MP FBI series can't be read as a standalone. The discovery that MP made, that I thought was just a bit too convenient at the very end of book 1, helping to exonerate Wes, makes another appearance (or few) here, and we get to hear the unsub's voice throughout the tale. We also find out that they/another unsub? want what's theirs back - this is cleverly done, and there wasn't a doubt in my mind as to what said voice was referring to. But, I was big time wrong as to their identitiy/ies and to what was wanted back. This author does beautifully with setting her scene and unsub/s.

The wolf character of the tale and the title sounded weirdly believable, to the point it had me pondering mental health as an illness versus delusions/indoctrination/cult. I'm still no closer to understanding the guy by the end of the tale, but suspect that he's done for in this series.

There is more than one thread being played out - to say how many would spoiler this tale. I was shocked and in a tiny bit of disbelief at the killer/killers' (?) identity/ies, how they could go undetected for so long and how no one noticed there was something wrong with them. Were they all that good actors? The ending was the teeniest bit unsatisfying because the issue of getting the victims to their graves wasn't explained enough. The blood sacrifice aspect, yes. The 'Imhotep'-ish bit, yes. But not the physical distance, and as the killer/s were described physically, unless their beliefs/delusions/indoctrination/cult absorption gave them superhuman strength, then no, that doesn't work.

Again, not spoilering here but it was nice to see a bit more of Wes in this book, seeing that distance and the storyline kept him mostly out of the thick of things. Could it happen irl without screams of compromise and without defence lawyers screaming "set up!"? Not sure.

And, thank goodness for motels in obscure little American towns that haven't been decorated or refurbished since the 70s, that provided a perfect means of self-defence and MP socking the baddie/s where it hurt. No shrinking violet, her.

Book 3 has seemingly already been written, as there's a full blurb at the end of this one. I'm so glad KW is such a prolific author, and that Storm Publishing know what a gem they have on their hands in her, as they don't delay putting her tales out, so I'm expecting the next in about 4-6 weeks going on the gap between books 1 and 2.

Big thanks to Storm Publishing, author Kate Wiley, and NetGalley for the ARC.

As the daughter of one of America’s most notorious serial killers, Margot is the Bureau’s expert at getting inside the minds of monsters. Wyatt Holmes, the most notorious serial killer who claimed that wolves had been talking to him, leading him to his prey, has been behind bars for a decade, convicted of hunting hikers like animals on the Appalachian Trail. While everyone's sure that he is responsible for the newly discovered skeletal remains, the burial patterns and the timelines do not match. As Margot dives deeper into the investigation, she discovers a horrifying truth: someone else is out there.

I must say that I will not forgive this book for keeping me up until I saw the sunlight. Was it because of the high tension? Maybe. But there were some other elements that hooked me. The mystery was definitely there, but beyond murder, the plot had ritualistic undertones that made it all the more intriguing. While some of the revelations were predictable, the majority of the mystery and the constant need to question everything kept up until the end of the book. The investigation process and the interactions between the characters felt natural and not forced, which is a huge plus and something I constantly look for when I read similar books. The plot was not rushed, and the tension built steadily until the end, so I did not feel overwhelmed by constant action.

Margot is a unique FBI agent, given her horrible past, being the daughter of a notorious serial killer herself. We see two sides of her as a result of her experience with her father: her toughened side and her traumatized side that triggers occasionally during investigations. As a protagonist, she felt real and relatable.

The author used a simple and accessible language throughout the book, so the reader can focus on the plot and the investigation completely. It is a great example of a book that hits the spot with great storytelling.

I would totally recommend this book (which is part of a series I am determined to go through the backlist of) to readers who enjoy dark, psychological crime thrillers with strong female FBI leads set in eerie, atmospheric wilderness.

This was my initial experience with the Margot Phalen series. Margot’s unique appeal stems from her being the daughter of a serial killer, providing intriguing psychological depth as she navigates the complexities associated with her family history.

In this installment, Margot and her FBI team investigate a grave site along the Appalachian Trail where seven victims remain unidentified. Margot suspects serial killer Wyatt Holmes but questions the accuracy of her intuition. She consents to meet Wyatt in his maximum-security facility to discuss recent events. However, upon meeting him, Wyatt does not exhibit the characteristics of insanity that Margot expected; instead, his responses are clear and straightforward.

Margot senses that Wyatt can perceive her innermost thoughts, recognizing traits within her reminiscent of himself—a realization that unsettles her and prompts reflection on her similarities to her own father. While initially believing Wyatt to be involved in the new grave site discoveries, Margot concludes he lacks knowledge about them, leading her to reconsider her investigative approach. As the inquiry progresses, it becomes evident that someone else may be responsible for the killings.

The narrative is engaging and features several unexpected developments. Although my experience allowed me to deduce the resolution ahead of time, I found enjoyment in following Margot’s journey and confirming my suspicions. Nevertheless, certain elements detracted from the overall experience. The dialogues between Margot and her colleagues felt somewhat contrived, and repeated references to “snort laughing” were unnecessary. Additionally, excessive detail at times disrupted the flow, requiring rereading for clarity, and could have been omitted.

Despite these minor criticisms, I found the story to be a worthwhile read. The issues noted did not significantly diminish the pleasure of engaging with the mystery. Ultimately, The Wolf at the Door is an absorbing mystery scheduled for publication on Tuesday, May 19, 2026, and will be available through major book retailers.

The Wolf at the Door is a taut, breath‑catching thriller that pulls you straight into the shadowed wilderness of the Appalachian Trail and refuses to let go. From the moment seven skeletons are unearthed, there’s a sense of something ancient and hungry stirring beneath the surface, and the novel leans beautifully into that primal unease.

FBI Special Agent Margot Phalen is the kind of protagonist who lingers with you. As the daughter of a notorious serial killer, she carries a darkness she’s learned to weaponise, and watching her navigate the blurred line between hunter and hunted gives the story its sharpest edge. Her expertise, her instincts, and the quiet ache of her past make her compelling in a way that feels both fierce and deeply human.

Wyatt Holmes, the convicted killer who once stalked hikers through the Tennessee wilderness, adds another layer of tension. Everyone is ready to pin the newly discovered bodies on him—until the evidence starts whispering a different truth. The burial patterns don’t match. The timeline fractures. And suddenly the trail Margot is following begins to twist into something far more dangerous.

The wilderness itself becomes a character here—vast, watchful, and indifferent. As Margot ventures deeper into the terrain where Holmes once hunted, the atmosphere tightens beautifully. You can almost feel the trees closing in, the silence sharpening, the sense that something unseen is tracking her steps. When Margot realises she’s become the target, the story shifts into a breathless, pulse‑quickening chase that’s as atmospheric as it is unsettling.

This is a thriller that thrives on tension, psychology, and the quiet terror of being truly alone with something that means you harm. Perfect for readers who love their crime fiction dark, character‑driven, and edged with danger, The Wolf at the Door delivers a gripping, wilderness‑soaked mystery that keeps its teeth in you long after the final page.

Title: The Wolf at the Door
Series: Margot Phalen FBI Book #2
Author: Kate Wiley
Publisher: Storm Publishing
Genre: Mystery/Thriller
Pub Date: May 19, 2026
My Rating: 3.5
Pages: 310

I followed the Detective Margot Phalen series and enjoyed it she is now with the FBI. A bit of background from the other series.
Twenty years ago, Ed Finch – America’s most notorious serial killer – used the Bay Area as his hunting ground.
His daughter Megan Finch now Margot Phalen was a homicide detective with the San Francisco Police Department.
Margo spent her whole life trying to forget her past. She has and still suffers from the PTSD that occurred to her when she found out her father was a serial killer.
She worries if this terrible knowledge – will she ever escape her so that she may live a “normal” life? However, her nightmare finally ended, and we now have a new series’


.
BTW Margo’s partner Wes the ‘good looking loveable Detective to unlikeable Margo’s nasty mouth personality ~ making them the Good Cop /Bad Cop team! I am delighted to say he is also in this new series.

In the series now FBI Margot Phalen continues her obsession of bringing serial killers to justice. In this story she and the team head to the Appalachian Trail when a case there seems tied to a case of theirs.

Random hikers are murdered and there seems to be no pattern. Margot talks to the man in prison who has been responsible for these murders, a man who believes wolves talk to him and he kills for the pack.
However, now bodies were found that were killed while he was already in prison. Seems there is another serial killer.

As I was almost sure there would a teaser for Book #3.
So, Yes, I am looking forward to “Sleeping Beauties ‘next in this series.

Want to thank NetGalley and Storm Publishing for granting me this eGalley.

If you haven’t read any of this series, I highly recommend you use all your book buying dollars to snatch up this series as well as the previous five books in the original series. Margot is such an insanely good character (one of my favorites). Kate Wiley really took the idea of fleshing out her characters to a different level because Margot Phalen is so much more than an FBI agent who studies serial killers. One of the things I like best about this series is not even the investigations, although that was the draw originally. A lot of it is also the interpersonal relationships and how Wiley took the time to develop all of the characters. It seems like she throws more on Margot’s plate with every book, and this one went beyond even that. In this one, Margot’s team ends up dealing with three cases, and not everything gets tied up in a neat little bow. The next book is set up nicely for a nationwide search for one killer, and he is really reminiscent of Sicarius from Criminal Minds Evolution. I’m so intrigued by this guy, I can’t wait to find out what happens in the next book. This really was a great book, and I only had one small issue with it, and in the grand scheme of things, it’s probably not even that important. But toward the end, Margot says something about wanting to curl up and watch a One Tree Hill marathon. And honestly, I just don’t see that happening, even if she did have injuries from being attacked. It just seems so outside of her character. I’m not suggesting she would get off work and jump right into a serial killer documentary, but I’m pretty sure One Tree Hill is not the show for her. Again, such a small complaint compared to how awesome the rest of the book is!

Huge thanks to Storm Publishing and NetGalley for sending me this ARC for review! All of my reviews are given honestly!

The Wolf at the Door — Kate Wiley
Format: ARC
Publishes 5/19/26
⭐️⭐️⭐️⭐️

Thank you to @netgalley, @stormbooks_co, and @katewileyauthor for the ARC.

The Wolf at the Door is the second installment in the Margot Phalen FBI series.

When seven skeletons are discovered along the Appalachian Trail, FBI agent Margot Phalen is convinced she already knows the killer—she’s studied him closer than anyone. But when the evidence doesn’t line up with the man behind bars, she’s forced into the wilderness to face a terrifying possibility: the real predator is still out there… and watching her.


I was really excited to get this ARC since I read the first book back in February, and this sequel absolutely held up. It’s a fast-paced, atmospheric thriller that pulls you in quickly and doesn’t let go.

The Appalachian Trail setting is used so well—the isolation feels real and adds this constant edge of tension, like something could go wrong at any second. Margot is a strong lead: smart, complicated, and still carrying the weight of her past in a way that feels believable.

What stood out most was how personal the story feels. The tension isn’t just from the case. It's tied directly to Margot. It becomes an unsettling cat-and-mouse dynamic where you’re never quite sure who has the upper hand. Definitely a must-read if you read the first book.


✅ WHAT WORKED
• Psychological depth — Margot’s past adds real weight
• Wilderness tension — isolation feels suffocating
• Strong investigative thread — clues stay engaging
• Hunter‑becomes‑hunted arc — sharp and suspenseful
• Villain ambiguity — Wyatt Holmes is deeply unsettling

———
⚠️ WHAT DIDN’T WORK
• A few slower mid‑book beats
• Some secondary characters could’ve used more dimension

This is the second of the Margot Phalen series where she is working for the FBI.
She mainly works from her ranch, but occasionally has to go to the office or to crime sites.
A mass grave has been found in a remote Appalachian area, and it looks as though one of the victims was buried alive!
A serial killer who operated in the area is in prison, but he left his victims out for the wolves.... not in graves.

Oh, Margot is such a character. Her past has made her into the woman she is, and while there is darkness in her, she is a good person, just needing to make the world a better place.

This book centres on a serial killer who has been apprehended, and who could not have been responsible for some of the victims in the grave, some are too recent.

Margot and her team have to figure out how the victims got to this remote site - a difficult climb up a trail.

Margot's gut instincts are always spot on. She senses danger before it rears it's ugly head - and in this book it saves her life.

How was she to know that she was a target?
It was a shock to me who the killer was - and the motive. Really creepy.

I don't want to give away any of this book's plot, but there are twists and turns that will grab the reader and like me, they will read far into the night, unable to put the book down.

Another fantastic Kate Wiley thriller - do yourself a favour and read the whole series prior to this, where Margot is a Homicide Detective. Will give you insight to what type of person she is, and why she is like she is.
I am so pleased she has Wes by her side, he is her anchor.

I have read them all, and honestly can't wait for the next instalment.

5/5 stars

I was SO excited for book 2 because I absolutely devoured book 1 and immediately dove into the entire Margot Phalen homicide detective series.

While I absolutely love this series and book 2 delivered in a lot of ways, there were a few things that left more to be desired.

I was shaking in my boots the way book 1 ended, and I was REALLY looking forward to getting more into the "orange bucket killer" as I like to call him. But I noticed it was not the main event of book 2 as I had hoped and expected. I felt like we were just given crumbs in regard to him so it was hard for me to really get into the story and I couldn't figure out why. Then around 40% in I realized why. I understand it's because this isn't technically Margot's jurisdiction, but now that she has been asked to assist with the case I really hope book 3 delivers.

Another thing I missed was the little town she lives in, with her farm and rescue animals. I LOVED that setting so much and I hope we can get more of it in book 3.

I think those were the main things that ultimately made me rate this 4 stars instead of 4.75 like book 1.

I didn't think this book was very twisty but I don't really need a bunch of twists to be honest. But if you're expecting this to be a very twisty thriller type book, it's not. It is, however, written well and a very great fbi series! If you like crime novels, or tv shows like Criminal Minds, you definitely need to check this out! This is definitely 1 of my top 2 crime series novels.

And also, "I want them back" was CRAZY.

Thank you Netgalley, Storm Publishing and Kate Wiley for the ARC.

Received as an ARC through Netgalley to review, this is an honest review.

Thanks to Storm Publishing for them pre-approval to read this book.

The Wolf at the Door continues extraordinarily the Margot Phalen series with bone chilling fashion.

This time for Margot and her colleagues, their serial killer could case brings them to Tennessee and to the winding, rugid Appalachian Trail; and to the woods and the wilds where murderer Wyatt Holmes made this stage of death. Being back deep into the actual field means putting one's thoughts into how in the HELL did Holmes kill for so long in such in an untamed place- given as the team learns- it takes so much physicality to achieve to kill in this trail, Holmes couldn't be behind a set of graves discovered deep within the woods. What Margot ( along with readers themselves ) that Wyatt Holmes is a kind of killer that while many will write off as crazy; Margot believes the way Holmes hunts his victims is to give back to "his" pack of wolves that her truly believes he was a member off. These haunting graves and unknown victims means the team has found something far more daunting: a serial killer no one knew of... until now. As the case twists into the unknown, unearthing the identities of the victims and understand a killer that's as comfortable as Holmes was in his own death space; the team becomes the hunted... and their killer wants what was his back buried in the ground. No matter how.

Unmasking this shadowy UNSUB means unlocking a darker links of a chain that would come to define a serial killer.

Highly recommended.

Such a great series that’s well written and engaging from start to finish. I’m a huge fan of the Margot Phalen series, and yet again this instalment keeps us completely on our toes.
Margot remains such a strong and compelling lead. Her determination, resilience, and instinct make her a character you can’t help but root for, even as the cases she faces grow darker and more complex. The tension in this book builds slowly and creates a gripping sense of unease that never really lets up from the very first page.
I’ve always loved Wes, her partner, and while I did miss seeing more of him like in the earlier books when they worked side by side in the police department, his presence still adds emotional depth to the story. Their dynamic continues to be one of my favourite aspects of the series.
It was especially intriguing to revisit the Appalachian Trail murders that were introduced in earlier books. Seeing this thread explored further added a satisfying sense of continuity and payoff for long-time readers. I had a small inkling about the culprit, but I couldn’t quite piece together why which made the reveal all the more rewarding.
As always, things are never quite what they seem. The twists are clever without feeling forced, and the pacing keeps you hooked throughout. Kate Wiley has a real talent for crafting dark, atmospheric stories that pull you in and refuse to let go.
This series has definitely become an obsession for me, so I’m incredibly excited to know there’s another book on the way!
If you enjoy dark, gripping crime thrillers with strong characters and intricate plots, this is absolutely a series you need to check out.

✨️ Thank you to the publisher and NetGalley for an early arc for a honest review.

As someone who did not read the first book, I absolutely loved this one and now will be going back to the start of the series and will be reading the next. If you are new to this series, while it is most likely beneficial to start with the first book, I really didnt feel like I missed anything because of how the author wrote this one, I just jumped into the life of Margot, a FBI Special Agent with a backstory that sets her apart from any other FBI thriller that I have read.

Margot is the daughter of a notorious serial killer, something that has made her a great FBI agent and also able to communicate and understand serial killers. She also has an edge to her, and her perspective throughout the book often has you wondering what will be the tipping point for her, which adds a great layer to her character and the story itself. The case that we follow Margot and her colleagues to a mass grave in the Appalachian Trail, numerous bodies and while they initially believe it to be an already named serial killer, Margot untangles an even deeper web.

This is a great thriller, I enjoyed the tension that is brought by the location of Appalachian Trail and also the uncomfortable feeling that each member of the FBI team seems to have in their own ways, this case really brought the push and pull vibe throughout. This book also has a psychological aspect as Margot is always having a deep internal battle within herself but also a battle of trying to solve her case without giving in to the darkness that lurks within her. Overall great story and characters and I cant wait for the next one.

This was my first by Kate Wiley, and now I’m officially invested! I’ll absolutely be circling back to book one in the Margot Phelan series because I can tell there’s so much more to uncover with her character.

This hit that sweet spot for me as a police procedural: methodical without dragging, tense without feeling overdone, and layered enough to keep me fully locked in. The investigation unfolds in a way that feels grounded and realistic, with just enough twists to keep you second guessing without veering into unbelievable territory. It’s the kind of story where the pacing quietly builds until you realize you’re flying through chapters because you need answers.

And Margot… she is complex, intuitive, and just a little bit haunting in the way she can slip into the minds of killers. Her insight feels almost instinctual, which makes her both fascinating and slightly unsettling (in the best way).

The Appalachian Mountain setting added such a strong, atmospheric backdrop. It was isolated, eerie, and rich with potential. You can almost feel the weight of the landscape pressing in on the story. That said, I did find myself wishing the local folklore and lore played a bigger role in the plot. It’s hinted at just enough to make you want more, and I think leaning into that could have elevated the story from great to unforgettable.

Overall, this was a gripping, moody procedural with a standout female lead and a setting that lingers. If you love getting inside the psychology of a case while following a strong, complex investigator, this one is definitely worth picking up!

The Wolf at the Door is the kind of thriller that sinks its claws in early and refuses to let go.

The premise alone is chilling, but what truly makes this story stand out is the creeping sense that nothing is as straightforward as it first appears. Every new discovery pushes the investigation further into unsettling territory, turning certainty into doubt and keeping the tension simmering just beneath the surface.

FBI Special Agent Margot Phalen is a fascinating character to follow. Her understanding of predators isn’t just professional—it’s deeply personal—and that perspective gives the story an edge that feels sharper than the typical crime thriller. Watching her navigate a case where the truth keeps shifting adds an intense psychological layer to the suspense.

The wilderness surrounding the Appalachian Trail becomes more than just a backdrop. It amplifies the unease, creating the constant feeling that danger could be waiting just beyond the next ridge. That atmosphere of isolation makes every step of the investigation feel more precarious.

Author Kate Wiley builds the story with a steady hand, balancing psychological intrigue with pulse-pounding momentum. The result is a thriller that feels both immersive and unsettling, pulling readers deeper into the mystery with every chapter.

Dark, tense, and impossible to ignore, this is the kind of read that will have thriller fans racing toward the final pages just to see how it all unfolds.

Special Agent Margot Phalen is back with a new mystery to solve. She is tasked with interviewing a serial killer behind bars who targeted those who traveled the Appalachian Trail. When a mass grave is uncovered, Margot and her team try to link the bodies to their killer. However, while in the small rural area, they are asked to help with a cold case from a local department that has a shocking connection that hits way too close to home for Margot.

Digging into a new book featuring Margot means curling up with your favorite blanket and preparing to be totally engaged and immersed in the story until you finish. With a fresh storyline and connections to the first book in this new series, the author does not disappoint us with her clever twists. I love that we still get to spend time with Margot’s former partner, Wes. I’ve always loved their connection! I also loved the way the team works together and each person has a different perspective to add. I love that you know the story will continue in the next book, but there’s not some horrible cliff hanger of an ending that is so frustrating. I can’t wait to see where Margot goes next in the ongoing investigation as well as what new things she will get herself and her team into! This author has quickly become one of my go-to favorites! *Thank you to the publisher and NetGalley for an advance copy of the book in exchange for an honest review!

The Wolf at the Door is another gripping triumph from Kate Wiley, delivering everything fans of her writing have come to love and a story that lingers long after the final page. At the heart of the novel is Margot Phalan, a character who continues to evolve in compelling and unpredictable ways. Margot is sharp, complex, and emotionally real, drawing you deeper into her world with every chapter. Wiley has a real gift for crafting protagonists who feel authentic, and Margot is no exception as she is the kind of character you invest in completely.

The Wolf at the Door by Kate Wiley is a very engaging thriller that blends suspense and psychological depth. I was immediately drawn into the story, especially getting back with familiar characters of FBI Special Agent Margot Phalen, Wes, Andrew, Sydney, Alana, and Greg. Margot’s unusual background, as the daughter of a notorious serial killer, adds a fascinating layer to her role as an investigator. Her ability to navigate the twisted minds of criminals is compelling, making her a standout protagonist. The author constructs a story filled with tension as Margot delves into the chilling case of the seven skeletons found along the Appalachian Trail. The way the author weaves together forensic details with Margot’s personal struggles kept me interested in what would happen and provided insight into the case and a deeper understanding of Margot’s motivations.

I was never truly able to guess who the culprit was until it was revealed as the author throws in clever twists that challenged my assumptions, making for an unpredictable and thrilling read.

Overall, The Wolf at the Door is a well-crafted thriller that kept me guessing until the final pages. With its intricate plot and a chilling backdrop, it’s a great read. I would recommend this book, this series, and this author.

ARC Review through NetGalley for The Wolf at the Door by Kate Wiley.

The Wolf at the Door is a breath catching thriller that pulls you straight in and doesn’t let you go until you’ve turned the final page. Kate Wiley absolutely nails that sense of primal unease from the very beginning, crafting an atmosphere so tense and immersive that it feels as though danger is always just out of sight, waiting.

What stood out most for me was FBI Special Agent Margot Phalen. She is the kind of protagonist who lingers long after the story ends. There’s a fascinating darkness within her, and watching her learn to harness and weaponise it adds such a sharp, compelling edge to the narrative. Wiley handles Margot’s internal conflict brilliantly, especially as she moves through the increasingly blurred lines between hunter and hunted.

The setting is also exceptional. The wilderness is rendered so vividly that it becomes a character in its own right; vast, watchful, and utterly indifferent. That backdrop intensifies every moment, amplifying the fear and isolation in a way that feels deeply unsettling.

This is a thriller that thrives on tension, psychology, and the quiet terror of being truly alone with something that means you harm. It’s atmospheric, gripping, and deeply unnerving in all the right ways. A strong four-star read for me, and one that will definitely stick with me.

The Worlf at the Door, the second FBI Special Agent Margot Phalen investigation story, was a yes for me! I listen to the first book in audio before I read this one so I was full in Margot and her team's story when I started this second book. It was an interesting polar and even if I figured part of the intrigue out, I kept reading and I was eager to confirm my suspicions!

In the book, we follow Margot and the rest of her team in their visit to Tennessee where human remains were found along side the Appalachian Trail. Margot and her team are flied in as cold case unit specialists to investigate these murders which are suspected to have been committed by an already behind the bars serial killer. However, the investigation take an unexpected turn and the FBI team, along side the local police, are brought on a trilling quest to solve the mystery.

Even if this is the second book of Special Agent Margot Phalen, it can easily be read as a stand alone. If there is an intrigue or part of a story from one of Kate Wiley other books, there is always just enough information shared for the reader to understand and to be able to follow. Overall, I am giving The Wolf at the Door a 4.5 stars as it kept me engaged throughout the story and I feel like it was easy to read and the connect to the different characters.

This one felt like stepping into the woods and realizing—far too late—you’re not alone.

The Wolf at the Door is sharp, unsettling, and relentlessly tense. It opens with a mystery that seems almost too easy to solve… and then slowly unravels into something far darker, far more complicated, and impossible to look away from.

What sets this apart is Margot. She’s not your typical investigator—she carries a past that adds an eerie depth to everything she does. The way she thinks, the way she reads people (and predators)… it makes every moment feel charged. You trust her instincts, but at the same time, you question everything—just like she does.

The atmosphere is incredibly well done. The Appalachian wilderness isn’t just a setting—it feels alive, watchful, and quietly threatening. There’s a constant undercurrent of danger, like something is always just out of sight, waiting.

And the twists? Genuinely surprising. Not just for shock value, but the kind that make you rethink everything you thought you knew. The tension builds steadily until the final stretch, where it completely takes off.

Dark, immersive, and deeply addictive—this is a thriller that keeps you looking over your shoulder long after you’ve finished.

Several bodies have been found in a mass grave on the Appalachian Trail, and the FBI believes them to be victims of Wyatt Holmes, a serial killer who hunted and slaughtered several people over many years. FBI Special Agent Margot Phalen is brought in to talk to him and get him to admit that they are his victims. But after meeting with him, she fears the worst – he wasn’t responsible for these crimes, so there is another serial killer out there.

As part of their investigation, they visit The Body Farm, otherwise known as The Anthropology Research Facility at The University of Tennessee. I’ve heard of this place and always thought it would be fascinating to visit, but the closest I’ll ever get is reading about it in books like this one. It’s really cool how they can determine the years (to a degree) each of the bodies was buried.

There are also more clues regarding the unknown perpetrator who buried a disturbing bucket that Margot discovered. Each story in this series provides more information about him as we see from his perspective, and I’m hoping he’ll become the main focus of a book soon!

My thanks to NetGalley and Storm Publishing for the free advanced reading copy of this book.

Thank you to NetGalley and Storm Publishing.
Once again, Margot is on the trail of a convicted serial killer and his yet-to-be-identified victims, but there is a new burial site and Margot isn’t convinced they are the work of the same killer.
The story picks up six months after the previous book, but provides enough clues to follow it even if you haven’t read the previous one
In this case, Margot not only has to interview the killer but, together with the rest of the team, must also find out who is responsible for these new murders.
Meanwhile, picking up the thread from the previous book, we continue with the plot involving the mysterious killer who murdered the teenager in her hometown and for whom Wes was accused.
Of course, I love the characters of Margot and Wes and how they complement and support each other. Alana is another strong point and I can’t wait to see how she performs in her new role in the next instalment.
The balance between action and more relaxed moments is spot on, making for a very entertaining and gripping read.
As always, the ending leaves everything set up to continue with this fantastic series, which I wholeheartedly recommend to fans of a good thriller featuring serial killers.

Thank you to NetGalley for the ARC of The Wolf at the Door by Kate Wiley

As a long time reader of this author and fan of Margot, I had high hopes going in and once again I was completely hooked. I flew through it and, as always, was left wishing it had lasted longer.

This instalment takes Margot onto the Appalachian Trail, where the discovery of an unmarked grave containing multiple bodies sets off a complex and unsettling investigation. What seems initially straightforward quickly becomes anything but, with links to past crimes and the involvement of Wyatt adding an extra layer of tension and uncertainty. The remote setting really stood out for me, bringing a sense of isolation that heightened the stakes throughout.

Margot remains a compelling lead and her partnership with Wes continues to be a real strength of the series. I have grown very fond of both of them and the wider cast, who add depth without ever distracting from the central plot.

The pacing is sharp and the tension builds steadily, with enough twists to keep things moving while still allowing space for character development. It strikes a strong balance between procedural detail and emotional impact.

Another gripping and atmospheric read that reinforces why I enjoy this series so much. A very easy five stars.
