Rating: 4.5/5 
 ***Minor spoilers*** 
 I wasn't sure what I was expecting with this book, but I was definitely delivered a great story. I was debating between a 4 and 4.5 rating, but as most reviews say, the ending was amazing, so I gave it 4.5. This book is a whirlwind (of the good kind) and a great read. 
 This book is about a girl named Ruby who lives in a world where children and teenagers either died of a disease called IAAN, and if they didn't, developed strange abilities. The government was scared of these children, and decided that they needed to control every single one of them. They brought them into camps where they were not allowed to use their abilities lest they face punishment. The first portion of the book shows a bit of Ruby's life before she was brought to the camp, and what living in the camp is like. 
 To be honest, the first few chapters confused me a bit. One chapter would be in camp, one would be before camp, and the jumps in time left me a bit confused. The story was actually quite slow in some places. The beginning was great, the end was amazing, but the middle just seemed to drag on, although there was some much needed character development there. It was a bit predictable in places but also surprising in others. 
 I loved Ruby as a protagonist, but sometimes she just seemed too naive. I think she wanted to see the best in people, and it screwed her over more than once. The teenagers in this book seemed real, and interacted with each other the way an actual teenager would. I found the book interesting from the beginning, but I only got super into it during the last bit of the book. The ending was great. (view spoiler)[ I was so sad! It reminded me of the end of Champion by Marie Lu. I wonder if he's ever going to be able to get his memories back, and if he does, would he forgive her? (hide spoiler)] Where the story wasn't interesting, I kept reading because I really liked the writing style and the characters. 
 This story was a great read, and I definitely recommend it to anyone who enjoys fantasy and/or sci-fi type books. Even if you don't I'd say give it a try, since you might like it. It's really worth reading!
