Twelve-year-old DJ Walters always knew there was something strange about the house across the street: toys mysteriously disappeared when they wound up on its lawn, and Mr. Nebbercracker himself acted like he had a secret to hide. But this Halloween the house has become a living, breathing monster, and people have started to disappear! The trouble is that no one believes DJ and his friends. So they vow to find out what's inside the house and how to defeat it. But can they do it before it destroys the entire neighborhood and gobbles up every trick-or-treater in sight?
