Julia Donaldson is the author of some of the world's best-loved children's books, including modern classics The Gruffalo and The Gruffalo's Child, which together have sold over 17 million copies worldwide, and the hugely successful What the Ladybird Heard adventures. Julia also writes fiction, including the Princess Mirror-Belle books illustrated by Lydia Monks, as well as poems, plays and songs - and her brilliant live shows are always in demand. She was Children's Laureate 2011-13 and has been honoured with a CBE for Services to Literature. Julia and her husband Malcolm divide their time between West Sussex and Edinburgh.

Kate Pankhurst lives in Leeds with her family and spotty dog, Olive. She has a studio based in an old spinning mill where she writes and illustrates children's books. Her projects have included the Fantastically Great Women series and Mariella Mystery Investigates series. Kate is distantly related to the suffragette Emmeline Pankhurst, something that has been an influence on the type of books she enjoys creating for children.
