The Dark Lord of Derkholm is a 1998 young adult fantasy novel by author Diana Wynne Jones. Once a year, a magical fantasy land receives guests from another world. These guests, whom visit as Pilgrim Parties under the organization of a ruthless businessman named Mr. Chesney, embark upon this journey to experience a real-life fantasy adventure, complete with dragons, battles between the forces of good and evil, and even a Dark Lord to vanquish at the end of their hard-fought quest. However, after years of suffering the devastating consequences, the people of this fantasy land have had enough. Maybe, if they completely sabotage this year’s tours, nobody will ever want to visit again. To do so, they’ll have to appoint the worst wizard for the job of Dark Lord. Unfortunately for Derk and his family, that’s him.
