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.

Holly Black is the author of bestselling contemporary fantasy books for kids and teens. Some of her titles include The Spiderwick Chronicles (with Tony DiTerlizzi), The Modern Faerie Tale series, the Curse Workers series, Doll Bones, and The Coldest Girl in Coldtown.

She has been a finalist for the Mythopoeic Award and for an Eisner Award, and the recipient of both an Andre Norton Award and a Newbery Honor. Her new books are The Darkest Part of the Forest, a return to faerie fiction, and The Iron Trial, the first book in a middle grade fantasy series, Magisterium, co-authored by Cassandra Clare. Holly currently lives in New England with her husband and son in a house with a secret door.
