This is the third book in the Witch & Wizard series. These books are young adult, supernatural thrillers.
This book is pretty dark. There is lots of horror, killing of children, mistreatment of animals, etc. The adults are either absent, evil, or ineffective, leaving the kids to try to take back the world. The book is full of simple symbolism with lots of children's book staple problems. I liked the first book in the series and like each subsequent book a little less.
