Good, diverting, but not great. My biggest complaint is somewhat spoilery, so I'll put it in the comments, but while this is an interesting take on a possession story, it reads a little too much like something a trying-to-be-edgy jerk I knew in college would have written. This novel has much more plot than I ever saw him muster, but it's similar in tone, theme, and visuals. The sheriff character makes little sense, nor do the tamagotchi/nano pets.
