Tony DiTerlizzi is a New York Times bestselling author and illustrator who has been creating books for over a decade.

From his fanciful picture books such as The Spider & The Fly (a Caldecott Honor book) to chapter books like Kenny and The Dragon and the WondLa trilogy, DiTerlizzi always imbues his stories with a rich imagination.

With Holly Black he created the middle-grade series The Spiderwick Chronicles, which has sold millions of copies, been adapted into a feature film and been translated in over thirty countries.

Mo Willems is a three-time Caldecott Honor winner for Don't Let the Pigeon Drive the Bus!, Knuffle Bunny: A Cautionary Tale and Knuffle Bunny Too: A Case of Mistaken Identity.

His books have been translated into over 25 languages, and his celebrated Elephant & Piggie early-reader series has been awarded the Theodor Seuss Geisel Medal on two occasions as well as five Honors.

Other favourites include That Is Not a Good Idea!, Goldilocks and the Three Dinosaurs and Nanette's Baguette. 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, USA.
