Query: This is cool

Ok, I have this book and It was great, It has a lot of good pictures of all the guys. Although some the facts are off, the pics a worth it and most of the book is acurate. If you like this book I'd also recommend, *N Sync with Justin, Tearin' up the Charts, and of Course, THe Offical Book!
