 Dear Barry Lyga: I hope that while you were writing this book, nobody took it upon themselves to look up your web history. I'm sure anybody who looked would find themselves slightly concerned for your wellbeing. On the other hand I know a ton of research must have gone into writing this book so I applaud you for that. 
 I have a soft spot for murder mysteries. I don't read many, however, because a lot of the well known ones are adult books and I generally don't enjoy those as much. As somebody who wants to study forensics and forensic anthropology in university, getting a glimpse into Jasper Dent's head is fascinating. Stuff like this always got me interested and this book did not disappoint. 
 I Hunt Killers follows Jasper "Jazz" Dent, son of a notorious serial killer who has 123 murders to his name. While other kids were being told not to be afraid of the dark, Jazz was being taught how to dispose of a body. Although his dad may be locked up in prison, he never leaves Jazz's mind, and always plagues his thoughts. When a serial killer shows up in town mimicking his father's first murders, Jazz is determined to prove that he's not like his father. 
 For the first portion of the book, I was pretty bored except for the investigative bits. It did get better and better as the book went on, though. This book strings you along and leaves you guessing about what could be behind everything or who the killer is. There are so many different levels to this book that there's almost no way you could predict EVERYTHING that went down, unless you're Sherlock Holmes or something. 
 When I found out who the killer was, I wasn't surprised, but it also wasn't the person who was at the top of my suspects list. I was surprised at what followed closely after, though. 
 Overall, this book was dark, mysterious, thrilling, and terrifying. I would definitely recommend it to anyone who enjoys a good murder mystery or crime book. However, if you're sensitive to gore or are easily disturbed, this isn't the book for you. If you plan to read this, go in expecting something VERY dark. If you're up for it, it's worth the read, without a doubt.
