Dan Gutman has always been a baseball fanatic. He played in Little League as a kid, and one of the first magazine articles he ever sold explained the science behind the spitball, the scuffball, and corked bats. When he thought about the T206 Honus Wagner-the most valuable baseball card in the world-he began to write honus & me, his first Baseball Card Adventure. Dan is also the author of the New York Times bestselling Genius Files series, as well as the internationally bestselling My Weird School series. Jim Paillot lives in Arizona (another weird place) with his weird wife and two weird children. Isn't that weird?
