Simon Bloom, The Gravity Keeper by Michael Reisman
This book was a lot of fun and a great read for anyone who likes science fiction. It was clean and appropriate and sure to please. In this story, the laws of science are controlled by special books. When Simon gets a hold of the book for physics he learns that he can control gravity! At first, his new powers are simply a source of fun, but when he learns about a dangerous plot to control all the laws, he will have to use his knowledge to stop the threat.
