Query: Gripping 'till the end!

This book was very well written. It kept my attention throughout the whole book. At first I thought this would be another boring book we had to read for school, because it was slow and confusing, but as I read on, I kept wanting to read more to find out what happened next. It was gripping until the end. I've heard when you ask questions about a book after you've read it that you are interested. I don't know if this is true, but if it is, then I was REALLY interested, because I was asking a million questions, and when it was all sorted out in my head I thought it was a very clever story.Cormier kept switching perspectives of the story which was very interesting. I enjoyed this book a lot!
