[Ruby · Rating 2 out of 5]

Unbelievably disappointing and extremely poorly edited. If you are going to write a book based in the States and the characters are American, do not use English or Irish colloquialisms ???

I had this issue with Idol as well and I’m not sure if Louise O’Neill is trying to break into the American market or something but her editors absolutely should have copped that Americans don’t generally say things like “I’ve sorted it” or “I reckon”, amongst other phrases.

Notwithstanding this, there is still the issue of the plot, which was very predictable and felt like a bit of a PSA for something that has been ongoing for YEARS now (and only scratched the surface). It also felt too modern with references to X, covid and DeuxMoi, not to mention the use of the term “unalive” instead of suicide ?! (this is a personal aversion that I have though so I can’t be too mean about it I suppose).

I have read every single LO’N book and this one has made me not want to read another. This does not feel like it was written by the same person who wrote Asking for It or The Surface Breaks. I did finish this in one day however I think this was intentional because I really, really wanted it to be over.

Happy publication to the new novel from bestselling Irish author Louise O’ Neill. I read Whatever Happened to Madeline Stone over the space of a couple of days on holidays, finishing it on the plane home today and of course I cried at the last paragraph. I am a noted sap but even with that, it is very good, I’m pleased to say.

Twins Madeline and Chelsea Stone are child stars; think the Olsens and you’re on the right track, except everyone knows Maddie shines just a little bit brighter than her sister and is destined to be huge. That is until Chelsea gets the role of a lifetime, one that should have been Maddies. Just as Chelsea is catapulted into the big time, her sister disappears, presumed dead. Fast forward to 2025 and a documentary is being made that stirs all the old gossip about the twins back up, not being helped by an online blackmailer who has found all sorts of personal information about Madeline and intends to use it against Chelsea. Although terrible secrets about their past could come out, Chelsea sees it as an opportunity to find out what really happened to her sister, and before long she’s spirally down memory lane.

Louise O’ Neill does social commentary really well and this book is no different. The early 2000’s were a rough time for young female celebrities and that’s fully explored in flashbacks throughout the story. I’d almost forgotten about some of it; upskirting, circles of shame on magazine covers, the constant building up of very young women just to gleefully knock them down.

What a bleak time.

Of course the present day depicted in the book isn’t always better either but I like to think things have somewhat changed.

This was a really addictive read; the tension builds expertly and even though you know Chelsea has done something awful, I couldn’t help but feel for her. Taken advantage of by a narcissistic momager, and an older male director, constantly objectified and never allowed to be a child, she’s very much the product of a toxic environment and doesn’t know any better.

I feel like millennials in particular will relate strongly to this one but it’s a compelling read either way. Recommend!

Out now!

Whatever Happened to Madeleine Stone – Louise O’Neill
⭐️⭐️⭐️⭐️⭐️ / 5

Thank you to Penguin Ireland for sending me a copy of this - I absolutely loved it.

Louise O’Neill has done it again. This book completely consumed me from start to finish, and I genuinely couldn’t put it down. It’s gripping, unsettling, and emotionally sharp in a way that only she seems to do so effortlessly.

The dual timeline works so well here, slowly peeling back the layers of Maddie’s disappearance while building this quiet, aching tension in the present. The mystery itself is compelling, but what really stood out to me was the exploration of fame, sisterhood, and identity - especially the complicated dynamic between Maddie and Chelsea. It felt so real and, at times, deeply uncomfortable in the best way.

Chelsea as a narrator was fascinating. There’s something almost hollow about her life in 2025, shaped entirely by grief, guilt, and the shadow of her sister. Watching her step back into the spotlight and confront the past was both heartbreaking and addictive to read.

O’Neill’s writing is, as always, incredibly sharp and atmospheric. There’s this underlying sense of unease throughout the entire book—you know something is wrong long before you fully understand what, and that tension never lets up.

And that reveal??? I genuinely did not see it coming, but it made perfect, devastating sense.

Dark, thought-provoking, and completely gripping - this is easily one of my favourite reads of the year.

[The Book Nook (Jennie) · Rating 5 out of 5]

From the very first pages, #whateverhappenedtomadelinestone brims with suspense and emotion, laced with a powerful sense of nostalgia. It’s a compelling, beautifully written read that doesn’t shy away from difficult, very real issues that feel especially relevant today. What stood out most was its sharp commentary on celebrity culture- and how, despite everything we know, it can still be deeply problematic. A thought-provoking, unputdownable read. 📚💭

[Aoife D · Rating 2 out of 5]

As with other Louise O Neill books, I think this would be better suited to young adult readers. It seems like the kind of book I’d have raved about as a teenager thinking it was hashtag deep.
The subject matter, i.e., toxic celebrity culture, child stars being exploited etc., has been done before and far better e.g., McCurdy’s book, and I don’t think this fiction work adds anything fresh or real to an already saturated field of media telling us that the noughties were terrible times. Also, considering its target audience was adults, I’m unsure as to why so much hand holding was required in explaining to us how awful it was. Though saying that, somehow it still managed to feel surface level in exploring those themes, making it somehow both over-explained and under-developed simultaneously.
I was intrigued at the start as to what Maddies two major secrets were, but both were teased so often throughout, they became increasingly obvious, so by the time they were ‘revealed’ it’s less of a twist and more of a confirmation.
I do think this would be a great book for younger readers, I’m just struggling to see why it was marketed for adults.

[Karen Barber · Rating 3 out of 5]

Since they were kids Erin Stone clung to the prophecy that her children would become famous. Granted, the same psychic had said one of them would die before she was thirty, but the quest for them to become child stars is on.
Madeline and Chelsea were instantly recognisable. Child stars, cute and happy to do what they were asked to stay in the spotlight. Unfortunately, while Chelsea became a star under the tutelage of The Director Madeline imploded. Rumours of drug taking and poor behaviour plagued her. And when she disappears her story becomes one of those mysteries the family cannot escape.
After retiring shortly after her sister’s disappearance, Chelsea has always wondered what happened to her sister. Years later it seems she could be about to get some of the answers she craved.
Chelsea’s big secret wasn’t such a big secret. There’s so much around this situation that feels wrong, with many who could have stopped things happening choosing to look the other way because of the lure of fame.
Thanks to NetGalley for giving me the chance to read and review this before publication.

[Nienke Schuitemaker · Rating 4 out of 5]

Had a great time with this! The dual timelines worked really well and as a millennial the same age as the twins, the pop culture setting felt very familiar to me. The mystery kept me hooked.

I saw someone say they felt this was predictable and they were disappointed by that, but I feel like the ‘predictability’ of the earlier timeline was the entire point. That’s the commentary. I thought it was handled well and I really enjoyed seeing older Chelsea come to grips with her younger self’s actions and reality.

The psychic element was such a good addition, too!

[Tracey Kennedy · Rating 5 out of 5]

Review of advance copy received via NetGalley. I loved this! Whatever Happened to Madeline Stone by Louise O’Neill is a gripping and assured novel that offers a different take on the complexities of the Me Too movement. The story is genuinely suspenseful, with convincing, well-drawn characters at its centre, particularly our protagonist, Chelsea Stone. While it explores dark themes, it never feels heavy-handed; the message is delivered with an efficient touch and cleverly entwined in the novel’s titular mystery. Distinct from O’Neill’s earlier work yet recognisably hers in its themes, this is a compelling and satisfying read. I am a long-time fan and this one was worth the wait.

[Sarah Faichney · Rating 5 out of 5]

Louise O’Neill is an instant, drop everything author for me. Her writing is consistently superlative. ‘Whatever Happened to Madeline Stone?’ is an excellent addition to her body of work. I devoured it! It's incredibly nostalgic for those of us who grew up in this era. O'Neill doesn't pull any punches and makes a great fist of exploring misogyny (especially within the mainstream media) impossible patriarchal beauty standards, exploitation and the sort of abhorrent behaviour that sparked the #MeToo movement. I think that Louise O'Neill excels especially in the illustration of grey areas. Few things are black and white in this story (as in life), which adds to the complexity of the characters. It's also a confronting piece of work. It really made me consider my own complicity. After all, if we didn't crave gossip and view successful, famous women through a Machiavellian lens of envy, would there be a global market for trashy tabloids and magazines? Perhaps we can all do better.

I'm gutted to have finished reading. I would love to hear a well-narrated audiobook version and surely the book will be optioned for film/television?🤞🏻Fans of Taylor Jenkins Reid will love this. I can't recommend it highly enough. Simply superb! F*ck the Patriarchy! All hail Queen Louise!

Louise O’Neill has done it again.

I’ve yet to meet an O’Neill novel I didn’t enjoy, but this one properly got its hooks into me. It’s sharp, addictive, unsettling, and absolutely steeped in that glossy, grimy early-2000s celebrity culture that so many of us remember a bit too well.

We move across decades here, from the 80s to the 2000s and into the present day, and it works so well. Right from the start, with Erin bringing her twin girls to a fortune teller and hearing that one child will be famous while the other will be dead by thirty, there’s this feeling of dread hanging over everything. You know something awful is coming, and O’Neill makes you sit in that discomfort all the way through.

Madeline and Chelsea Stone are child stars shaped, pushed, packaged and used by everyone around them. Their mother is all ambition and projection, but she’s hardly the only one feeding off them. Agents, directors, friends, the whole machine of fame, everybody wants a piece. One sister rises. One sister spirals. Then Madeline vanishes just as Chelsea’s star is taking off, and the fallout of that ripples through the next twenty years.

What I really loved was how this is more than a mystery. Yes, the disappearance keeps the pages turning, and yes, I was hooked from the first page, but the real strength of the novel is in what it says about fame, identity, exploitation and the damage done to girls who are turned into products before they’re old enough to know themselves. It’s bleak in places, and rightly so.

Chelsea is such a compelling character too. Not always likeable, not always easy to sit with, but full of guilt, hunger, grief and that awful pull of the spotlight. Her voice carries the whole thing.

It’s glamorous and poisonous, sad and gripping, and full of that precise, cutting social commentary O’Neill does so well. A quick read, but not a slight one.

If you love stories about child stardom, fame gone rotten, messy family dynamics and dark early-2000s nostalgia, this one’s well worth picking up.

Thank you to the publisher for the opportunity to read an advance copy via NetGalley; all opinions my own.

“Fame, and the things people would do to get it, to keep it. It was a sickness.”

Twins sisters Madeline and Chelsea Stone are joint stars of the AtomicKids sitcom Double Trouble, but everyone knows Maddie is the star. That is until Chelsea is chosen for the role everyone believed Maddie would get. As Chelsea’s fame reaches dizzying heights, Maddie vanishes.

Ooh this was so good I loved it! An unflinching account of the world of child stars, shown as both an opportunity but also an exploitation. I loved the writing and how interviews, diary excerpts and blog posts were used here and there to tell the story.
There’s a real air of unsettling nostalgia in the chapters detailing the past as the twins rise to fame and a reminder of how dark Hollywood can be. I’d forgotten how toxic the celebrity gossip blogs were back then and millennial readers will really remember these!
I thought it was a really addictive and compelling read about the dark side of the world of child stars and celebrity, the hunger to not only achieve fame but the desperate need to hold onto it.
Erin, the girls mom was the epitome of “momager”, and a truly unlikeable but fascinating character. Everything she does is in her own interest and her lack of maternal instinct is stark.

The present day is 2025 and Chelsea has stepped away from the limelight and lives a privileged and private life. That is until a storage unit filled with Maddie’s belongings is found and Chelsea has to face the events of the past and the secrets she has spent years hiding.
I had such conflicting emotions surrounding Chelsea’s actions, feeling sorry for her at times and then flipping to disgust.
There are some unanswered questions at the end which I found a little frustrating but an overall brilliantly addictive story.
4.5🌟

[Bookworm Express Kwan · Rating 4 out of 5]

There’s no business like showbusiness, and Whatever Happened to Madeline Stone is an insightful story about a former child star in an industry that consume young and talented people and spit them out for entertainment.

Chelsea and Madeline Stone are twin sisters and stars of Double Trouble, a series at AtomicKids. Both girls decide to audition for the role of a lifetime, but it is Chelsea who gets the part. While Chelsea’s star rises to fame, Madeline’s fall from grace is all over the place in the tabloids and juice channels, until she disappears.

Years later, a storage room is found, containing Madeline’s stuff from the year she disappeared, and Chelsea is determined to find out what happened to her twin.

I was HOOKED from the first page, the suspense was good, for sure, but what stood out were the psychological observations around fame. It touches on the many reasons people go to lengths for stardom, but also on the toxicity of a system that exploits and disposes young people.

The characters were, arguably, a tad on the nose, in the sense that they were almost (emphasis on almost) stereotypical - but it didn’t bother me too much as there was enough story to back things up. It showed how the system punished whoever stood up for themselves and rewarded those who fell in line, that is, until the people decided you were no longer desirable.

That’s why it felt especially satisfying when Chelsea FINALLY stood up and did what was right for her.

Highly entertaining!

[Laura · Rating 4 out of 5]

Whatever Happened to Madeleine Stone is an entertaining, fun read with some serious themes throughout.

Twins Chelsea and Madeleine are child stars in a sitcom for kids, with a selfish mother and a premonition from a fortune teller (that they don’t quite believe, but their mother does) hanging over them. The fortune teller predicted when they were just babies that one of them will become a hugely famous star and the other will be dead before 30.

Things become difficult when Chelsea gets a part in a new show and Madeleine’s career starts to freefall. Madeleine goes missing - presumed dead - and 17 years later Chelsea is still haunted by what might have happened.

This is partly a mystery, but it mostly focuses on the life’s of the twins and those around them. There are tricky family dynamics and the perils of fame at a young age, mixed with the heavy expectations (on women especially) to behave a certain way.

Although Whatever Happened to Madeleine Stone isn’t particularly gritty or hard hitting, it made some good observations about celebrity culture and I got through it quickly. This book is an entertaining and enjoyable read - a good holiday read.

3.75 stars bumped to 4/5

[bowiesbooks · Rating 3 out of 5]

The plot of this book really grabbed my interest - a mystery to be solved with social commentary about the influence of the Naughties on women? Right up my street.

The first 30% definitely had me hooked, with the set up of what happened to Chelsea's sister, Maddie, being teased out in the first few chapter's. This story is told on two timelines - one in the years before Maddie's disappearance when they were children, and a current timeline in which we see Chelsea try to maintain the 'perfect' life she has set up for herself. These shifting timelines kept the narrative going well and definitely added an air of suspense and mystery.

I liked the pop culture references initially, but after a while they came to be too much for me. After the first several examples of the how the Naughties was a horrendous time for female celebrities - weight loss, body checking, drugs, sex headlines etc - I felt like the author didn't trust that the I as the reader would be able to get the gist from there. Though it is definitely shown in the character's actions, it was told more, leading me to feel like it was being constantly overexplained rather than letting the story and the character's speak for themselves. The ending was predictable but this wasn't necessarily a bad thing, it was quite fitting.

[Caitlin · Rating 4 out of 5]

I’d give this a solid 4 stars. I was immediately drawn in by the mystery surrounding the missing twin, Maddie, especially with the backdrop of both sisters having been child stars and one achieving major success before the disappearance. It definitely had that page-turner quality at the start that kept me hooked.

What really kept me reading, though, was how relatable it felt in terms of the media culture I grew up with, reminiscent of the era of Mary-Kate Olsen and Ashley Olsen. The book does a great job exploring the darker side of fame at a young age, the pressures that come with it, and the #MeToo movement, offering some sharp social commentary.

I wouldn’t say I found most of the characters particularly likeable, but they were well developed and felt realistic, which made their stories compelling in a different way. Overall, I found it to be an enjoyable and thought-provoking read.

Thanks to NetGalley and Random House for the advance copy.

I was excited to read this story about two famous twin child actresses, growing up in the 90s/00s spotlight (definitely a lot of Olsen similarities!)

It started really strong but unfortunately I felt the story began to drift and by the end I wasn’t hugely invested. Thank you anyway for the ARC.

Could not put it down, absolutely addictive.

[Kellie Tallant · Rating 4 out of 5]

I love Louise O’Neill’s books and am hooked in from the start. I really enjoyed ‘Whatever happened to Madeline Stone’. One small thing that pulled me out of the story, though, was the use of Irish sayings in dialogue, despite the characters being American. It felt slightly out of place at times.

[Rebecca · Rating 5 out of 5]

This book was genuinely unputdownable! I was so absorbed by Chelsea‘s experiences. The story unfolds across two timelines - the twins lives on TV in the early Noughties, and Chelsea seemingly perfect life in 2025. It touches on a lot of really interesting themes, from the treatment of child stars, to the dissection of women in the media, and the intricacies of sisterhood and female friendships. I remember the early 2000s very well, and the rise of reality shows and gossip blogs. I really enjoyed the way that Chelsea looks back on her teen years with a critical gaze, but still acknowledging the societal expectations today aren’t always much better. I loved all the layers of the mystery, as people’s perfect facades were peeled back.

This book is perfect for fans of stories about Hollywood glamour, the dark side of fame, and explosive tell-alls.

[Saffy · Rating 4 out of 5]

I absolutely love Louise O’Neill’s writing so was thrilled to have the opportunity to read Whatever Happened to Madeline Stone. It’s set over two time lines - the early 2000s and 2025 when ex child actor Chelsea Stone finds herself once again in the spotlight 20 years after her twin sister Maddie’s disappearance. O’Neill writes so powerfully about the impact of fame on women and the abuse and manipulation of child actors. If you’ve read Jeanette McCurdy’s memoir this is familiar territory but it doesn’t make it any less powerful. I did feel that about halfway through the plotting weakened and I became a little frustrated with the character of Chelsea. However the final quarter of the novel really picks up once Chelsea finds her voice and this section is a compelling read that left me breathless by the end.
Recommended.
Many thanks to NetGalley and the publisher for the opportunity to read and review this digital ARC.

[Emma O’ Shea · Rating 3 out of 5]

Please ignore the change in rating, I had read too many Bridgerton books which lowered my standards.

[Rachel · Rating 3 out of 5]

Although there was a sort of breathless urgency to Chelsea’s narrative – both in the past and present – that propelled the reading experience, on review, her lifestory is somewhat unconvincing. This is probably because she’s a composite of a lot of real people, as her sister, the titular disappeared Madeline, is also a composite. I’m likely only recognising some of the components, given how many comparisons there are in reviews to Jeanette McCurdy’s memoir, but the obvious ones are: the Olsen twins; any teen actress who had a ‘countdown to eighteen’ clock or an upskirt paparazzi shot on her eighteenth birthday; Katherine Heigl; Grimes. The problem for me is that the composites don’t meld together very well. Yes, having twins play both sides – one the people pleaser who swallows the abuse as the price of entry, one the contrarian who dares to have opinions of any kind and gets blackballed as ‘difficult’ – at least allows for both stories. But maybe that’s the problem. Maybe both stories needed their own breathing room.

Chelsea’s storyline in the present feels like it is often sacrificed for the storyline of the past, because the past is far more interesting and less morally dubious. Chelsea berates herself throughout for terrible mistakes she’s made, which boil down to trusting people who she believed had her best interests at heart, having an affair with a younger man after her husband cheated first, and having a fight with her sister where she said the kind of mean and shitty things all siblings say to each other at some point (it is truly the most brutal of relationships). At no point does she ever emote much over what it means to marry someone as rich and exploitative as Nick (there is no such thing as an ethical billionaire, even if the book doesn’t address this). Nick doesn’t appear to be aligned with Elon/Zuck/Besos in 2026 (maybe because instead of buying his competitors and ruining the products by prioritising shareholder returns he is still trying to make a rival actionable), and the question is – why? Every techbro is now showing his rightwing colours these days, what makes Nick different? The thing is, the story needed a method for Chelsea to live in splendid isolation, but … just retiring from the public eye would have been sufficient? Think of all the people who faded away without even wanting to. If she’d been willing to move to the Midwest, or a different country, she truly could have stopped being famous without marrying a rich man. There’s a couple of points where she uses his money, but given that Erin and Kelly betray her anyway, and the websites continue anyway, and Chelsea chooses to do her own detective work anyway, I feel like the need for grotesque wealth could have been written out. Have Chelsea pay off her dependents with her residuals. Don’t give a key witness to the ‘mystery’ soap-opera dementia. Etc etc. I mean, I’d be pretty confident O’Neill isn’t on the side of the billionaires here, but this was a big blind spot.

There’s another aspect that didn’t sit comfortably for me, and it’s the various points at which Chelsea or the narrative berate someone for ‘stealing’ plot points from real people’s lives. In particular, Erin writes a screenplay about her daughters’ early success. I can fully understand Chelsea’s sense of betrayal here, but … what is this book if not the exact same thing? I hesitate to say it’s ‘exploitation’ to use the Olsens, for example, to explore the concept of the dubious nature of child labour in Hollywood, but it cannot be denied that they are the immediate progenitors. Maybe the Olsens would feel some kind of way about this book, even if it’s on their side? To some extent, all literature is cribbing from real life. Quite a lot of novels are autobiographical, which means the loved ones of the writers are collateral damage. Equally, there’s a throwaway line about the children in influencer content and their treatment being equivalent to child actors, which is also concerning to me. I don’t approve of child influencers, but given the situation – it’s their parents filming and directly profiting – it’s a way gnarlier situation in one way, but also safer in another. Aside from the very fact of it being a form of abuse (if that’s your opinion), being filmed by your parents for doing cute shit is not inherently unsafe and exploitative the way an open set with sex scenes is, for example. Really it’s not the filming so much as the wide sharing that’s the problem, whereas – as O’Neill shows – the rot is in every level of the film set.

It leaves wide open the question of whether child actors should exist at all. If you’re saying child influencers shouldn’t – which I agree with – then the obvious corollary is child actors shouldn’t either. There are so few salutary examples of child actors having fulfilling and healthy lives and careers, and so many cautionary tales, that it seems obvious, if presenting huge difficulties to portraying many stories on screen. But the book doesn’t posit this.

Finally, although the title asks whatever happened to Madeline, we never really find out. The ‘clue’ about her death perhaps having been exaggeratedly reported is tenuous, and we only have it confirmed in the final line. I want to know what she’s been doing, because she’s obviously navigating her exit from fame and infamy far better than Chelsea, and presumably without having married a bad man/billionaire to do so.

[Aperson · Rating 3 out of 5]

This was a very middling reading for me, and a slight disappointment, too. I am very interested in behind the scenes of movie and tv, the whole showbiz machinery behind. Throw in twin kids, as well as what looked to be the fictional equivalent to Charlie's Angels... how could it be so bland? And I guess that's kinda the point with showbiz, or with her existence in it, but does the book about showbiz have to feel as vapid as Hollywood itself? O'Neill have a tendency to tell, not show. She does so in this book, as well as in earlier works. Sometimes tell is a very good thing (hot take), but here, these awful things that some people have done, read like a Wikipedia entry. Louise O'Neill always has something to say, but what is she trying to say or do here?

I am usually more interested in world-building and atmosphere than in plot, and here, I especially wished that O'Neill had written more about the acting experience and the show that she was on. There were descriptions about the characters that she (Chelsea) plays, as well as scenes from set, and I just wanted much, much more of that. This book could have easily been longer, and benefitted from it, by laying out the landscape, painting a picture rather than suggesting. Making it meticulous; making it worn. Someone once used a coat-hanger to describe this phenomenon if you like, whereby you describe something by comparing or alluding the thing you are describing to something else that you know very well, such as a brand-name. Those familiar names and words, those are the coat-hanger. Then, the more you describe, the more that coat-hanger becomes a proper coat-hanger, because now you are spinning clothes that can hang onto, and those clothes are all the words that you used to expound upon your description of the hanger. Sorry, I thought I could explain it better and in less words, but my point is that the descriptions in the book are very much like coat-hangers without clothes. More name-dropping than descriptions. Honestly, I feel I am being tad too harsh here. Just because I wasn't able to conjure images in my head of what it looks like, does not mean that the problem is lack of clothes, metaphorically speaking.


Who is the Director? Who is Christopher? Who is blackmailing her? Whatever happened to Madeline Stone? What did Chelsea do to Madeline that fateful night? These are mysteries that are gradually revealed, and the resolutions are okay. They check out, but I wonder if I had felt compelled to continue reading had I not read and liked other books of hers. I found all(!) the bad guys less than stellar. Most of them frothing as their schemes slowly unravelled, as their boring motives were revealed (they did it for the money, or the fame). Especially disappointing is it to learn about this very crucial relationship that the author eventually divulge only a few pages. This relationship is something that defines Chelsea as it is something she wants, irregardless of the others, and which may cost her everything. The relationship between the two sisters is strong, and easily the best thing about the story, hence I liked the book. No wonder Chelsea was jealous of Madeline, because she seemed to have such an awesome personality. I was initially interested in the mysteries too, because I believe in the author, and I thought the answers would be more compelling than they ended up being. It is, beyond my criticism, still very much what characterizes a Louise O'Neill book to me: an antiheroine who craves validation; people around her who talks and talks, while MC looks at herself in the mirror and doesn't recognise, and other selfish denizens who happen to be her loved ones. I love, love that O'Neill always gives us these characters who just talk and talk nonstop, and it is not necessarily because it relates so much to the plot, but it just lends realism to the story, and it is usually very comfortable, like gossiping with a good friend, or two. I don't know exactly the reason why I did not like this book nearly as much as I have other books of hers, and if I find out, I wanna write it down.

(PS) Another grating aspect with this book is the ending, in which 8 % of the book (I read it in Google books, so they gave an exact percentage of how far in you are) is an excerpt from another book of hers, which makes the totaling amount of pages even less. As mentioned before, this is one book that could arguably be much fatter. With no exaggeration on my part, I would have loved this to have been twice as many pages.

Fame, and the things people would do to get it, to keep it. It was a sickness.

2 1/2 stars. This book wasn't terrible, but given that O'Neill's books are among my all time favourites, it was a huge disappointment.

The pacing was off from the start, nothing like the addictively propulsive Idol. Despite having Chelsea's secrets teased constantly (“the worst thing I’ve ever done”), the first half is a terrible slog. I have to admit I couldn’t imagine anything she might have done that I would find that interesting, which made me unsure what I was reading for or needed to be concerned about. I don’t think it ever built enough momentum around the secret, so the stakes felt low. And either her sister was long-dead, as had been thought, or she was alive. Neither possibility felt particularly concerning.

The story inhabits two worlds— that of the early 2000s in which Chelsea and Maddie are child actors, and the present (2025) in which Maddie has long been missing, presumed dead, and Chelsea is now retired, married, and mother to two kids. Then a website pops up posting pics of never before seen notes written by Maddie, followed quickly by an attempt to blackmail Chelsea. If she doesn't play along, her secret will be revealed.

The subject matter is timely, to be sure. Right now in 2026, we’re paying close cultural attention to the early 2000s. The fashions are back, the predators are being smoked out, and an overdue conversation about celebrity culture— particularly the treatment of young women and girls —is being had. This book explores that toxic early noughties celebrity culture— the culture that destroyed Britney and gave millions of girls eating disorders.

It is a classic "ripped from the headlines" story, reflecting on this specific time and place. From Milo James— an early noughties blogger of the Perez Hilton variety —to the twins' overbearing mother who encourages their eating disorders, very reminiscent of McCurdy's mother in I’m Glad My Mom Died. I think if you’ve been paying attention to the news there will be no surprises in this one. And while everything the book says is true— parents shouldn’t be allowed to force kids into fame; there’s a whole ecosystem enabling abuses in Hollywood —I don't think it adds much to the conversation or finds a compelling new way into it. Books like The Comeback were telling similar stories 6 years ago.

I'll still read whatever Louise O'Neill writes next, but the combination of poor pacing and well-worn subject matter made this one a miss for me.

Four years after her last novel, Louise O'Neill is back with her trademark social commentary and this time around she is going to task on nightmarish celebrity culture of the early 2000s. Centred on twins Madeline and Chealsea Stone as they start out as child stars thrust into stardom by a pushy stage mother and their tumultuous journey into early adulthood culmulating in Madeline's disappearence as she battled addicition and public shaming while her sister's fame rose higher and higher.

O'Neill is a master at creating unlikeable and complex female characters who frustrate you yet you still can find a lot of empathy for. This book expertly demonstrates how the twisted world of fame, money and the need for validation can cause people to hit the self-destruct button and drive them to make terrible decisions. Hollywood and gosspip forums are unforgiving spaces, but no more so during the early 00s where celebrities, the majority of who were young teens who were barely adults, were picked apart for their looks, weight, fashions choices and behaviour and fed to the public like lambs being led to the slaughter house. For any millenial reading this book, there's no doubt uncomfortable flashbacks will be triggered as memories of living through this period are not easy to forget.

However, while the book does it's best to highlight the awfulness of that celebrity era, the story itself feels rather suface level and not fresh? We don't come away with any new thoughts or ideas about this period that haven't already been discussed in-depth by pop culture writers or numerous op-eds in the last six years. It's obvious this novel is inspired heavily by Jennette McCurdy's sensational memoir; 'I'm Glad My Mom Died' and certain chapters and characters feel like a fictionalised version of real-life people. In a post#MeToo world, the public are well aware of the bad behaviour of Hollywood players and the horrendous treatment of its young stars so a lot of the scenarios in the book aren't as shocking as they probably should be. At times, the story feels oddly PSA-y towards its readers unnecessarily so, almost not trusting the audience to understand the reality and implications of public consumption of celebrity.

For once, this is a book that could benefit from being longer to allow the story to develop a real emotional core which is somtimes lacking across the pages. At times certain plots feel rushed without allowing the characters to breathe or for us to understand the motivations or actions of the characters.

Nonethless, this is an enjoyable read with O'Neill's sharp and fluid writing creating an engaging story and a stark reminder that we're a lot more complicit in the world of public shaming than we think we are.

I received an ARC of this book thanks to NetGalley and Random House UK, Transworld Publishers in exchange for an honest review.

Whatever Happened to Madeline Stone? tells the story of Chelsea Stone, an ex-child actor who is now struggling with her adult life. Chelsea used to act with her identical twin sister Madeline but they grew apart when Chelsea beat her for a key role and Madeline went off the rails. Now Madeline has disappeared and Chelsea is left wondering what happened to her sister.

Louise O'Neill has a talent for writing stories which tackle the difficult aspects of being a woman and I was looking forward to her take on child stars. Unfortunately, I kind of felt this book was about the wrong twin. Chelsea is an interesting character but her main purpose as the protagonist is to allow for the mystery of what happened to Madeline to drive the story. In terms of the biting social commentary and emotional grit that I love in O'Neill's work, Madeline would have made for a much better main character. Instead of getting a close look at the darker side of child stardom, these dark aspects are experienced second hand by the narrator. This means that a lot of the emotional gut punches are muted and don't quite land.

Putting that aspect aside, the general plot is a little messy too. It took me longer to get into this book than it normally does with O'Neill's work and I think that's partially due to the mismatch between the present day plot and the flashbacks. The present day plot flirts with being a thriller but stays solidly as a contemporary drama. Neither plotline fully explores its events either and this combines with the problem mentioned above to weaken the story further. A good example of this is the twin's mother, Erin Stone. She is a complex and interesting character to explore and yet she is a little sidelined and the emotional payoff of her story never really makes it to the surface.

Overall, I did enjoy this book and I really admire what it was trying to do. I think it was a bit messier and a bit less emotionally impactful than I have come to expect from the author. I also suspect that the marketing may draw in some thriller audiences who will be disappointed. If you want a thoughtful exploration of the exploitation of women, I think O'Neill's other books are unfortunately a better pick

Overall Rating: 3.5/5 stars

In 1988 a fortune teller predicts that two year old twins Madeline and Chelsea Stone will not only be beautiful but also famous, however, only one will reach the age of thirty. By 2002 the twins are stars of a sitcom called Double Trouble but of the two it’s Madeline’s star that shines the most brightly. However, most unexpectedly, Chelsea gets the role of a lifetime and now the brightest spotlight shines on her, her career goes stratospheric and then as her rewards come, Maddie disappears. By 2025, Chelsea is married and lives an empty but privileged life away from the spotlight. Unexpectedly, news hits the media of a storage locker that contains items that belong to Maddie and the story is back, centre stage. Worse still, it seems as if someone knows the truth, and is threatening to spill several secrets and Chelsea’s carefully curated life might just implode.

This is a mixed bag read for me although it does have a good, intriguing premise. It’s strong on control exerted over the young twins by their ambitious mother Erin and later on by a director. BUT is there anything new here in the light of all the revelations from #MeToo?? It makes thoughtful points about the culture/cult of celebrity and the damage that it can do especially at a young age. Again, it’s not exactly something new to hit the headlines. I find the most interesting narrative is that of the present day as it’s here that various things come to light and there are some very good scenes. I especially enjoy the final one in the studio to which I give a round of applause. The characterisation is strong although inevitably few are likeable as you would expect in a story of this nature.

However, it’s slow paced and there are lulls in the storytelling where not a lot seems to happen. This is especially true of the second half although it definitely picks up towards the end. I don’t think it ever feels especially tense and it should. It jumps around a lot in time and so that gives the narrative a disjointed feel. The ending doesn’t come as a huge surprise as all the signs point to it.

Overall, I like this author but unfortunately this one just doesn’t fully resonate with me but it is well worth a read.

With thanks to NetGalley and especially to Random House U.K./Transworld for the much appreciated early copy in return for an honest review.

‘Whatever Happened to Madeline Stone?’ by Louise O'Neill is a fast-paced and engaging novel that pretty much does what it says on the tin, so if you like the sound of it from the synopsis, chances are it will be a good fit. The only thing not made clear in the synopsis is quite how much eating disorder content is present in it, and although the content feels appropriate to the characters and their story, and no numbers are mentioned, anyone on the fence about whether or not it might trigger them would do best to avoid it.

I found the writing fluid and the story interesting enough to keep the pages turning. The pace is very quick—a little too quick at times, as the sudden jumps in time, either from one scene to the next or from present to past and back again, can be disorientating, especially as there are often no time indicators (e.g., ‘now’, ‘back then’, etc.) or space breaks. Sometimes it felt like a flashback hadn’t reached its point before I was catapulted back to the present again.

Although the book doesn’t add anything to the conversation around the issues raised—such as the exploitation and abuse of children and women in the entertainment industry, the misogyny and racism present in the industry, the prevalence of eating disorders and addiction amongst former child-stars, and the toxic nature of the blogosphere and parasocial relationships—seeing it from Chelsea’s point of view does give a human face to it, which I appreciated.

As for the mystery element, I found it intriguing enough—though, it ended up predictable (even its predictability was predictable…). The ending also felt rushed and anticlimactic. Still, I enjoyed the story overall. Not a book I will reread or remember, but a good bit of entertainment that fulfilled my expectations. A three-star read.

Many thanks to NetGalley, Louise O'Neill and Bantam for the ARC.

|#Netgalley| Published April 9th

Whatever Happened to Madeline Stone? is the much anticipated upcoming fiction release from Louise O'Neill. Louise is well known for writing pithy, biting social commentary. Stories about misogyny and how women's bodies are commodified, about the pressure society places on young women to appear a certain way.

It comes as no surprise then, to find that this is more of the same. This story centres around a pair of former child stars, twins Chelsea and Madeline Stone. Chelsea is now married with children and a lavish, enviable lifestyle. Madeline disappeared almost twenty years ago without a trace.

The opportunity to do a reunion for the TV show that made Chelsea a star seems too good to pass up - but that's exactly what Chelsea's doing. Her husband doesn't want the publicity, she doesn't want to go back there. She has moved on. But all eyes are on her anyway when a blog appears online, documenting the contents of a storage locker full of Madeline's belongings.

We go back and forth to witness the twins' rise to stardom, and the fallout after one soared and one sank. With commentary on how women in the industry were treated (that whole "virginity countdown" phase in the early 00s was truly warped), and a callout for the audience who remained hungry enough to keep Perez and his pals in a job, we're left asking - what really did happen to Madeline Stone?

Reminiscent indeed of "I'm Glad My Mom Died", but also of a book I read recently ("Honey" by Isabel Banta), this won't be groundbreaking for anyone who paid attention in the early 00s. For those of us who remember the upskirt pictures of Lindsay getting out of a car, or Britney brandishing an umbrella at a paparazzo, or Perez threatening to out someone - there's little here to shock.

It's definitely very readable, but I felt that it was immediately obvious who was behind everything and that took me out of the story slightly as I waited for that person to be uncovered.

CW for Eating Disorder content & abusive men.

Thank you to the publisher (who I won't tag) for granting me approval via @netgalley.

Whatever Happened to Madeline Stone is the kind of novel that slips under your skin from the first page. Louise O’Neill takes the glitter of early‑2000s child stardom and peels it back to reveal the bruises beneath—the rivalry, the pressure, the impossible expectations placed on two young girls who never had a chance to grow up out of the spotlight.

In 2002, twins Madeline and Chelsea Stone are the adored faces of Double Trouble, but everyone knows Maddie is the star. When Chelsea unexpectedly lands the role that should have been Maddie’s, the balance between them shifts in ways neither fully understands. And then Maddie disappears, just as Chelsea’s fame explodes. The world becomes obsessed with the mystery, but for Chelsea, the loss is far more intimate: a wound that never stops aching.

By 2025, Chelsea has stepped away from acting, but she can’t escape the legacy of being the sister who stayed while the other vanished. When a storage locker is uncovered containing painful remnants from the year Maddie went missing, Chelsea feels something she hasn’t allowed herself in two decades—hope. To follow the trail, she must return to the past she’s spent years avoiding and step back into the spotlight she’s tried so hard to outrun.

The novel moves fluidly between timelines, capturing the intoxicating chaos of child fame and the quieter, more complicated grief of adulthood. O’Neill writes with sharp emotional clarity, exploring the bond between sisters—how it nurtures, how it wounds, how it shapes the people they become. Chelsea’s journey is both heartbreaking and compelling, a search not just for answers but for the version of herself she lost along the way.

This is a compulsive, conversation‑starting read—glamorous on the surface, devastating underneath, and ultimately full of the kind of truth that lingers long after the final page.
