Dan Gutman may be weird, but he is also beloved by kids, parents, and teachers across the country. His books include the My Weird School series (more than 23 million copies sold), the Baseball Card Adventures (more than 2 million copies sold) and the New York Times bestselling The Genius Files. We also publish his spoofy picture book, Casey Back At Bat, and one of Dan's favorites, Johnny Hangtime. Dan lives in New York (a very weird place), with his weird wife, Nina. Jim Paillot lives in Arizona (another weird place) with his weird wife and two weird children.
