Operation Hope

Stephen Potts is a British author of children's books, particularly historical adventure novels set at sea. He took up writing for children in the 1990s, beginning with a loosely connected trilogy collectively known as The Running Tide. The three books cover the period from the mid 19th century to the present day, and are variously set in Britain, Greenland and the Aleutian islands. In March 2007 he was commissioned to adapt Philip Pullman's 1992 novel The Butterfly Tattoo (previously published as The White Mercedes) as a feature film.
