From an early age, Kate Thompson wrote and illustrated picture books, and was determined to be a children's author. However, she became a solicitor, which contained disappointingly little sleuthing or storytelling. Happily, following the birth of her sons, Kate rediscovered her passion for picture books and writing. She now lives by the sea and spends her days gleefully immersed in literary adventures of her own making.
