Query: This is the BEST book ever!

I was so excited when I got the book! I read it as soon as I got home and finshed it in like 2 hours! I don't know how to describe it! It was the best book I have read in my entire life, and I'm a heavy reader! This book kept me on the edge of my seat! As soon as I finshed it I e-mailed all my friends about the book! I would recomend that everyone should read this book. If they don't they're missing out on a lot of exciment! :)
