In her youth she was diagnosed with dyslexia and her intelligence was therefore questioned. This led her to leaving school, but going on to study painting at the London Art School and the Royal Academy School. After this she worked in painting, arts and crafts, photography and graphic design. She also married a sculptor who encouraged her to write children's books after seeing her talent at telling stories to their children. This led to her interest in writing, although she decided she preferred writing for adults.
