Why was the book so unputdownable? Quite frankly, it was because of the mystery. You see, Cassie is a natural profiler (she can read people very well). And after her mother was killed, well, she's never gotten over it. But after she joins the FBI's program to train other Naturals like her (natural in statistics, in detecting lies, in reading emotions, etc), a serial killer (who might have killed her mother) comes after her.
And it was to find out who the killer was that made the book so irresistible to me.
Plus, every now and then, a very short chapter is presented in the killer's point of view, and that definitely made me very very curious. I was given all these little clues, and I still didn't manage to figure out the killer!
I think that the whole aspect of the Naturals was really interesting. I know that the whole power thing is a bit worn by now, but these kids, well, I can sort of believe them. What abilities they have are really just highly developed intuition after all. I mean, think about it, most staff on crime shows seem to have the same kind of intuition.
The only thing that I didn't like about the book was the love triangle. It wasn't insta-love (thankfully), but she was stuck between: a. Mr Broody and Emotional (who has a crazy 'sister' protecting him and b. Mr Sarcastic and Troubled. Basically, two guys who gave lousy first impressions (but are apparently very nice). I would have been so much happier if the book just focused on Cassie, her past, and her trying to settle in.
Hopefully this is a series, because I'm really looking forward to the next one!
