It's hard to review this book. I really liked the first 100 pages, there was so much going on and everything was exciting. And then it stopped. Then the novel was all about Chloe, who's institutionalized. Then at the last 80 pages, the action picked up again. That means that you have about 200 pages in the middle with nothing going on - except for Chloe talking to the other people at the institution. Dull!
In the end it's clear that this book is first in a series; there's a cliffhanger at the end. Unfortunately though, it just felt like a very long prologue! I won't be reading the rest of this series.
