It was okay. The teen slasher concept was interesting and that element of it was well done, but the main character I thought was rather annoying. She moves to Nebraska because of a "dark secret" that is quite a letdown when you finally learn what it is. The killers motive is weak and pretty much as soon as you find out what it is the book just ends. There is no denouement whatsoever. It just ends.
All in all, a fine unique read that's a bit disappointing but also enjoyable enough given the unique concept.
