The Mists of Avalon by Marion Zimmer Bradley.

Even readers who don't normally enjoy Arthurian legends will love this
version, a retelling from the point of view of the women behind the
throne. Morgaine (more commonly known as Morgan Le Fay) and Gwenhwyfar
(a Welsh spelling of Guinevere) struggle for power, using Arthur as a
way to score points and promote their respective worldviews. The Mists
of Avalon's Camelot politics and intrigue take place at a time when
Christianity is taking over the island-nation of Britain; Christianity
vs. Faery, and God vs. Goddess are dominant themes. (description from
