Query: It was a book you never want to put down.

It was a totally cool book. It related to all ages from kids to adults. It was exciting threw the hole book not just in the begining or end. It was a book that could satisfy everyone's needs from Mystery to romance to horror. It was a fiction but could be beleavable. It teaches valuable lessons for life and teaches Teens not to do anything stupid. It is a graphical book but it is not overdone. That is hard to find in books now-a-days. I love all of Lois Duncan's books but this is the best. My other favorite book is also by Duncan. It is called Killing Mr.Griffin. It to is perfect in every way
