Ros Asquith started out as a photographer, became theatre critic for Time Out, City Limits and the Observer before emerging as a cartoonist. She has had a number of cartoon books published, and her strip, Doris, was a regular feature in the Guardian.

Ros wrote and illustrated the best-selling Teenage Worrier series about the angst-ridden Letty Chubb, which has been translated into more than ten languages. Besides writing and illustrating her own books, she has also written picture book texts illustrated by other people, and illustrated children’s books written by other authors, such as Anne Fine, Dick King-Smith and Francesca Simon.

She lives in London with her jazz critic partner and their two sons. She has stroked a tiger, cuddled a wolf, caught an escaped tarantula and juggles in a travelling circus, but mostly prefers reading, eating fudge and trying to learn the violin.
