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 Song from Somewhere Else (illustrated by Levi Pinfold), the Fizzlebert Stump series, and the CILIP Carnegie and Kate Greenaway Medal long listed The Imaginary (illustrated by Emily Gravett). He lives in Reading with a stand-up comedian and two cats. Katy Riddell is a young and imaginative illustrator with a BA Hons in Illustration and Animation from Manchester Metropolitan University. She grew up in Brighton and was obsessed with drawing from a young age.

Plenty of encouragement from her parents, both artists and illustrators, led her to spend hours writing and illustrating her own stories, which her father (former Children's Laureate and award-winning illustrator Chris Riddell) collected throughout the years. Originally drawn to Fine Art, Katy rediscovered her love for illustrating children 's books in her gap year and decided to pursue it as a career. Since graduating, Katy has worked on a variety of commissions including Pongwiffy by Kaye Umansky (Simon & Schuster) and Ever After at the Oxford Story Museum as well as developing her own projects. She loves working with children, and currently runs an art club at her local school. She lives and works in Manchester.
