Query: This book is the absolute coolest book I have ever read!

This book totally rocks! In my opinion it is the best book so far, but they're all good. I don't think it's possible for any of them to be bad. Sci-fi readers will enjoy this book, and even if you don't like science fiction you should pick up this book. It may not be as horrible as you may like to think. (P.S. Any Animorph readers feel free to email me!)
