This is one of the creepiest books I have ever read. Zach and his stepmom, Judy, see ghosts, and they have to hunt off one who wants to kill them. The reader gets to hear from lots of different people, and the narrator changes from chapter to chapter. For example, the first chapter is about Billy O'Claire, Zach is in the second chapter and Judy is the main character in the third chapter. I thought it was amazing how the author told a different story in each chapter and they all fell together in the end. This is a great "can't put it down" book, that is worth reading even if you don't think you like spooky ghost stories.
