Jeanne Willis wrote her first book when she was five. After that, there was no turning back. She has since written more than three hundred books and has won several awards, which are arranged in the attic where she works along with her collection of caterpillars, pink-toed tarantula skins, and live locusts. Jeanne Willis lives in London.

Jarvis is the illustrator of Poles Apart; Alan’s Big, Scary Teeth; and Pick a Pine Tree. Before creating his first children's book, he had lots of different jobs, including bingo caller, bouncy-castle painter, record-sleeve designer, and animation director. Jarvis particularly loves children's books — what they can do and how they can be kept and loved as little treasures.
