The Forest House

Blurb

The Forest House is a fantasy novel by Marion Zimmer Bradley and Diana L. Paxson, though the latter is uncredited by the publisher. It is a prequel to her best-selling Arthurian novel The Mists of Avalon.
The plot of The Forest House is based on that of the opera Norma, relocated from Gaul to Britain, but sharing the basic plot outline of a love affair between a Druidic priestess and a Roman officer.
