Bill Doyle is the author of Attack of the Shark-Headed Zombie and Behind Enemy Lines, as well as many other books for kids-with over two million copies in print. He has also created lots of games for Sesame Workshop, Warner Bros., and Nerf. He says, "My happiest moment as an author was when the genius Master Escapologist sent me a secret message offering me the job to write his incredible books." (No, he's not just saying that because the Master Escapologist is writing this biography!) Bill lives in New York City.
