A.F. Harrold is an English poet who writes and performs for adults and children. He spends his time showing off on stage, writing poems and books, and stroking his beard (it helps churn the ideas). He is the author of the Fizzlebert Stump series and the CILIP Carnegie and Kate Greenaway Medal longlisted The Imaginary , illustrated by Emily Gravett. He lives in Reading with a stand-up comedian and two cats. Emily Gravett was born in Brighton. After leaving school with few qualifications, she spent eight years living on the road before getting a place on the BA illustration course at Brighton University.

She won the Macmillan Prize for Illustration with Wolves , which was published to great acclaim in August 2005, winning many prizes and marking the beginning of an international career creating extraordinary books for children. She lives in Brighton with her daughter, partner and two rats.
