The Gravity Keeper

April 1, 2008
Gr 4-7-Simon Bloom, an average sixth grader who has made a habit of keeping his head down and out of trouble, discovers a "teacher's edition" physics manual that allows him to control gravity, velocity, and other physical properties. With his newfound powers, along with some new friends, he must face a rogue member of the mysterious Order of Physics who seeks to overturn the laws of nature. Part "Harry Potter," part "The Hitchhiker's Guide to the Galaxy", with a hint of "Goosebumps" thrown in for good measure, "Simon Bloom" is a solid choice for the intended audience. The book has a standard plot and characters that rarely rise above one-dimensional; what saves it is the playful yet respectful way that Reisman integrates actual physics into the story. While his characters are running around fighting people with ridiculous names, they are also learning about Newton's laws of gravity, motion, and velocity. With its mixture of humor, fast-paced action, and science fiction, this book will certainly appeal to many readers. Hopefully, it will get them interested in learning more about the real science, not the kind that enables kids to fly or shoot electricity, but the kind that still does some pretty cool things."Steev Baker, Kewaskum Public Library, WI"

Occasionally breaking into the story with a first-person comment, this books omniscient narrator tells the story of 11-year-old Simon Bloom, who one day discovers a mysterious, hidden forest in the middle of his New Jersey town. Followed by timid Owen, Simon enters the clearing where a secret, powerful group, the Order of Physics, has just met and disbanded. The adventure begins when a large book pops out of nowhere and decks Simon. Entitled Teachers Edition of Physics, the book is filled with scientific formulas that Owen figures out how to use, much like magic spells. His increasing skillshe learns how to control gravity and frictiondraw the attention of smart, popular Alysha, who joins Simon and Owen in marveling over the books secrets. Together, they must fight against a mysterious woman whose body is tattooed with scientific formulas and who is trying to take over the world. This is great, escapist fare for those smart middle-grade readers who are fascinated by science, magic, and adventure.(Reprinted with permission of Booklist, copyright 2008, American Library Association.)

Simon finds a teacher's edition physics textbook that grants him control over the laws of the universe. The story is told by a self-aware, intentionally didactic (though unintentionally grating) omniscient narrator who's dragged kicking and screaming through the fourth wall by Simon and friends. This derivative but entertaining adventure rejoices in its fast-paced, affectionate silliness.
