Mother and son Jean and Jamie Illingworth live in North Yorkshire with husband/father David John. Jean is a safety consultant and landscape photographer and Jamie an illustrator. They have had three children's books published previously (the Danny Dragon series), but this is their first collaboration on a full-length children's novel. They really enjoy working together, discussing characters and plot twists and details of the illustrations. Jean writes the story and then Jamie offers wacky suggestions that take the story in another direction. Jean attempts to describe the pictures in her head and Jamie then draws them far better than she ever imagined.
