So lucky to grab an ARC of this. Absolutely phenomenal suspense and horror novel for teens. With a main character so afflicted by constant fear, Carman's writing lets you feel every bit of it. You'll spend the entire book thoroughly creeped out. 
 Carman sets up a complex main character who refuses to interact with his peers, and at the same time the secondary characters manage to be well-developed as well. Will sees everyone as a potential villain, but the real villains are definitely not who he expects. The twist at the end will surely surprise you. 
 In the end this book is about more than a scare, or a plot twist. It's about the nature of fear, of overcoming it, and its true value. There's even a bit of a bittersweet romance thrown in. 
 Highly recommended for ages 12 and up, especially teen boys who will love the action and relate to Will.
