I think this book was actually really good. I only had a few problems with it. 
 First problem, it was kind of weird to me that they didn't fall in love in this book. They fell in love before the start of the book. Which made me feel a little bit disconnected from the romance. There were flashbacks to other times with them, but I still didn't feel like I knew how they felt about each other. 
 Another problem, a couple times when Ember was thinking about something, Chase would answer her like he could hear her thinking. I mean, if this happens once in a book that's no big deal but sometimes it seemed oddly like he could read her mind. 
 Now things I liked: There was some good action and stuff. Ember really seemed to know how to get herself into bad situations, and Chase always seemed to be there to get her out, but that sort of counts as fighting action and stuff. 
 I liked Chase. He was kind of scary and a little bit mean and knew how to send his mixed emotions of whatever, but I still kind of liked him. He was very honest. 
 Overall I think it was a good book and everything. I just had a few "?" moments.
