Jonathan Stutzman is an award-winning children's book author and filmmaker. His work for children includes the bestselling Tiny T. Rex series as well as Llama Destroys the World illustrated by Heather Fox, Bear Is a Bear illustrated by Dan Santat, and many others. The only magic trick Jonathan knows is how to make donuts (and other tasty foods) disappear. He lives in Pennsylvania, where right now he's most likely reading or thinking about new stories.
