Claustrophobic gated community. Overly friendly neighbors. Creepy kids. Putrid smells. Sleep paralysis. And trees that maybe aren't only trees.
Psychological and mysterious. There are clues dropped throughout as to what's really going on - some subtle, others not so much - and when it's finally confirmed, the story wraps up pretty quickly, in a way I wasn't totally satisfied with, but I'm still glad I read the book.
