A novel by Diana Wynne Jones. The Moor is home to three peoples. Normal people live in the Mounds, and farm and hunt. The Dorig live in the lakes and rivers, and are tricksy and magical. (The Dorig regard themselves as normal people, and refer to the people of the Mounds as "Lymen".) Giants live on the far reaches of the Moor, and no sensible person has anything to do with them.
