This was a great book but I couldn't understand Gabriel's love for Shay. It occurred very quickly and seemed to have no real basis except she accepted him as a vampire (which was not surprising in the circumstances) and she saved his life. 
 I also hated Shay's attitude to her BFF Olivia. Her secret resentment of Olivia was completely unfair and unworthy of her. She just seemed to ignore any point of view or feelings other than her own.
