There isn't much to say about this book, really. This series seems to be romance-driven, so when Anna and Kaidan are not together, it starts to fall apart. And since Kaidan doesn't appear until much, much later, the first half of the book dragged. The second half was considerably better, but there was still barely any plot to talk about. It was all Kaiden and Anna, their sexual tension and hot (for a YA book) make-out sessions, with some things happening in between that should have felt important, but just didn't. 
 Still I think the book was worth reading, exactly for the chemistry between the leads. I like Kai and Anna is okay too, I guess.
