Query: Fantastic!!!

This is my favorite book! I'd believed that it was a stand alone book for years before I found that it was actually part of a series; This book is so good that I haven't actually read any of the other books because I don't want to be disappointed by them. Based on reading difficulties and book content, I'd say that it's good for 7th graders and older; the older I've gotten the more I've picked up in the book.
