Probably one of my favorite books when I was a young teenager. It's a murder mystery story that keeps you on your toes. I think the best part of this book is that nothing is what you expect it to be so you are always surprised when new answers turn up. Another entertaining thing about this book is that you can "play" along taking the clues and trying to work them out in order to see if you, the reader, have the talent to solve the mystery. I really recommend this book to the young teenagers who are fans of Agatha Christie books, Nancy Drew books and maybe even a few Edgar Allen Poe mystery fans.
