A.F. Harrold is an English poet who writes and performs for adults and children. He spends his time showing off onstage, writing poems and books, and stroking his beard (it helps churn the ideas). He is the author of The Song from Somewhere Else (illustrated by Levi Pinfold), 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. Mini Grey studied sequential design at Brighton University before launching her first picture book, Egg Drop, in 2002. Trained in puppet making, set design, welding and carpentry, Mini's style has an unconventional flare and instantly recognizable quirkiness.

Mini has now published thirteen picture books. Amongst numerous nominations and prizes, Mini has won the Smarties Book Award and the CILIP Kate Greenaway Medal for The Adventures of the Dish & Spoon .
