Simon Bloom, Gravity Keeper by Michael Reisman ****

This book is about a boy named Simon Bloom (apparently) who goes into a grove of trees that shouldn't be there and accidently finds a book that tells how to control physics. So, he and some friends start to use some of the "formulas" and find that some people want to get their hands on the book. Now they are trying to keep the wrong people from getting their hands on the book.

I recommend this book for ages 9+.
