Peter studied languages at Oxford University, England, and lives in Devon with his wife Lucy and their two children. After a career as a non-fiction editor, he turned to writing for children soon after the birth of his son Theo. Egmont published his very first children's book, the bestselling A Lark in the Ark, which was shortlisted for the Red House award and the inaugural BookTrust Book of the Year awards. Peter also wrote King Jack and the Dragon, which was shortlisted for the Kate Greenway Medal and selected as one of the American Library Association's Notable Books of the year. Among his other titles, the hilarious The Great Dog Bottom Swap was shortlisted for the Roald Dahl Funny Prize, which he won in 2011 with Cats Ahoy!
