The Forest House is a fantasy novel by American writers Marion Zimmer Bradley and Diana L. Paxson, though the latter is uncredited by the publisher.

The novel revolves around the Druidic priestesses who serve the Goddess and keep the ancient rites of learning, healing, and magic lore in their sanctuary, The Forest House.

Lhiannon, one of the remaining priestesses, re-establishes a new sanctuary at Vernemeton (Most Holy Grove), or The Forest House, which is partially controlled and protected by the Romans.

Eilan knows their son, Gawen, whose bloodline comes from the Dragon (Celtic royalty), the Eagle (Roman Empire), and from the Wise (Druids), will play a crucial role in Britain's future, and makes great sacrifices to protect him in his youth.

The Mists of Avalon, a retelling of the King Arthur myth from a feminist point of view, is Marion Zimmer Bradley's most famous single novel.
