Philip Pullman's writing is full of mystery and adventure - of parallel universes, daemons and armoured bears. Darkness Visible explores this epic world and the diverse creative influences of Pullman's brilliant work. Written by acclaimed critic Nicholas Tucker, and packed with exclusive photos, illustrations and fresh material from recent interviews, this is both a celebration of Philip Pullman and an absorbing guide to all of his books.

Nicholas Tucker is the author of nine books about children, childhood and reading, including The Child and the Book, (Cambridge University Press, 1981 and 1990). He has also written six books for children, broadcasts frequently and reviews in the national press. He lives in Lewes, East Sussex and sometimes finds himself reading aloud the same books to some of his eight grandchildren as he once did to their mothers and father.
