This book has a few interesting things going for it, and a lot of irritating things going against it. The supernatural elements were a jumble, the action was decidedly non-young-adult, and the dialog was grating. Teens may talk this way, but none I've known.
The first book of a series needs to have a solid ending, this doesn't. While there were some good ideas here, there's no way I would read any further books that follow this. 1.5 stars. Bleh.
