Overall, I really enjoyed this book. Although I'm pretty sure I'm a little older than the target age group. I found the characters to be believable for the most part. However, some of the interactions between the characters were not. 
 This was a pretty easy read. Perhaps even too easy. Even if this book is intended for a younger audience, I don't think think it has to read as such. So, I felt it cold have been a bit more challenging and/ or thought provoking. Especially given the twist at the end. Thaddeus' character could have provided the perfect opportunity for this. 
 I wish the relationship between Keegan and Rourk had had a bit more time to develop. But maybe that happens in book two?? 
 I would certainly recommend this book to others.
