Query: I didn't want to put it down!

This was, in my opinion, the best book I've read recently. The age of the characters makes it easy to relate to them, for a young teenager. I like the fact that they could be any of my friends, since they seem so normal. The plot was filled with suspense and treachery, and I was so nervous I almost screamed at some parts - I won't reveal which ones! I highly recommend this book and hope you enjoy it as much as I did!
