This book is about a little girl who finds a pendulum , and she uses it on kids at her schools carnival, as well as friends. The story starts out creepy enough, but doesn't really conitinue that way. It starts out with a creepy old man with a cart, and we only see him once in the book at the beginning, and then she dreams about him one time. He is creepy and this character could've been developed a whole lot more. That part was very dissapointing. This book wasn't has creepy as House of Illusions, put nonetheless, it was good. In fact it wasn't as creepy as it could've been. Bad things start happening to those who have betrayed young Heather 'cause of the pendulum. The lesson that is the basic plot of this whole book is the lesson: What goes around comes around. This could be a modern day fairy tale. I'm not sure if the penedulum has anything to do with the werewolf in the story. I felt like this book had kind of a "lost" plot at times. One question is never answered by a character, why was Heather suppossed to have the pendulum? This is never clear. Around the middle of the book it kinda drags, but then picks up again until the end. The ending is really exciting.
