I reviewed this book when I initially read it a few years ago. Below is my original review! 
 Intense. Really intense. Kids are eating pets, kids are about to kill each other, people are getting sick, it's a mess. Sam, still love the kid. Caine, I have begun to form an even bigger soft spot. I love Caine, and feel so bad for him, and ugh. I want to hug him and make him happy. 
 Anyway. This book kept me on the edge of my seat, as much as the first.
