** spoiler alert ** 
 It was very interesting in a different way. One thing that I found really nice about it was that it wasn't predictable. 
 Things that I found unexpected: (don't read this unless you want SPOILERS) 
 (in no specific order) 
 1. Martin. Throughtout the beginning he acted as though he really truly cared about Shay, and sure once in a while I got that weird urge that something about him was up... but it still surprised me when he didn't want to put the knife down to help Shay when Gabriel was threatening to break her neck. 
 2. Shay is half-vampire. That does explain why she happened to be inlove with drinking Gabriels blood, I was starting to wonder about that. It does answer alot about who her father is, and to find out it's Sam... wow. 
 3. Shay actually finds Gabriel in Martin's office (I know this should fit in with #1). I was like, "No Way..." That would explain all the blood that Martin kept giving her during her transfusions. 
 4. I didn't get Shay's friendship with Olivia. I understand that Olivia cares about Shay, it's really nice. What I didn't get, and kinda thought was irritating, was the fact that Shay kept badmouthing Olivia. Then she kissed Kaz, which yelled out total "What the hell did she do that for?" I think that Olivia really truly thought of herself as Shay's best friend, but Shay was always hating on her. In the end she did follow what Shay wanted her to do and acted like the friend that Shay needed. 
 ... 
 All in all, I thought this book was interesting. Of course I'm awaiting the sequel, because the ending just left me begging for more!
