Claire was born in Bath in Wiltshire and moved to Kent when she was five. She spent her childhood trying to be Monet; carrying her paint box and easel into muddy fields, painting disinterested sheep and their acquaintances.
Claire got a Degree in Fine Art in Canterbury then moved to London in 1995. She stumbled through various jobs until settling down as a portrait painter and children's book author/illustrator in 2003. She now teaches others how to write and illustrate and lives in Crouch End, North London with her partner and her two daughters.
