The Dark Lord of Derkholm, simply Dark Lord of Derkholm in the United States, is a fantasy novel by the British author Diana Wynne Jones, published autumn 1998 in both the U.K. and the U.S. It won the 1999 Mythopoeic Fantasy Award for Children's Literature.The novel is a parody, for its setting is a mock high fantasy world, similar to that Jones covered in The Tough Guide to Fantasyland (U.K., 1996), a humorous travel guide on the Rough Guide model. The story continues in Year of the Griffin and the two novels have been called the Derkholm series (which the Internet Speculative Fiction Database (ISFB) does not explicitly link to The Tough Guide).
