Premise: A reporter found a powerful A.I. (from the future) in a hourglass form and he is going to use the power of this 'magical hourglass' to go back in time in order to save his dying wife before the family curse which the wife and her family have been suffering with kills her!
Said family's curse caused a mass murder from 40+ years ago with 10+ people getting killed, if the reporter wants to break the curse, he must go back in time to solve this 'Locked Room Mystery + Impossible Crime' level of mass murder, how will this adventure go?
The Time Traveler's Hourglass is a delightful mixture of Sci-Fi and crime & mystery story, despite its many characters the story is still neat and easy to understand. Plus the few main characters are well written enough, as well.
Although which is a bit nontraditional, but overall I'm pleased with this novel and how the murder mystery is explained! Will keep an eye on more of this novelist's works!
