Mo Willems' acclaimed picture book debut celebrates 20 years!When a bus driver takes a break in this hilarious Caldecott Honor-winning picture book, he gives the reader just one instruction: "Don't let the pigeon drive the bus!" But, boy, that pigeon tries every trick in the book to get in that driving seat: he whines, wheedles, fibs and flatters. Will you let him drive? Told entirely in speech bubbles, this brilliantly original and funny picture book demands audience participation!

Mo Willems is a three-time Caldecott Honor winner for his picture books Don't Let the Pigeon Drive the Bus!, Knuffle Bunny: A Cautionary Tale and Knuffle Bunny Too: A Case of Mistaken Identity. His celebrated Elephant & Piggie early-reader series, which now comprises 25 titles, has been awarded the Theodor Seuss Geisel Medal on two occasions as well as three Honors. Other favourites include Goldilocks and the Three Dinosaurs and That Is Not a Good Idea. Before he turned to children's books, Mo was a writer and animator on Sesame Street, where he won six Emmy Awards. Mo lives with his family in Massachusetts, US.
