The Mists of Avalon is a 1983 historical fantasy novel by American writer Marion Zimmer Bradley, in which the author relates the Arthurian legends from the perspective of the female characters. The book follows the trajectory of Morgaine (Morgan le Fay), a priestess fighting to save her Celtic religion in a country where Christianity threatens to destroy the pagan way of life. The epic is focused on the lives of Morgaine, Gwenhwyfar (Guinevere), Viviane, Morgause, Igraine and other women of the Arthurian legend. The Mists of Avalon is in stark contrast to most other retellings of the Arthurian tales, which consistently cast Morgan le Fay as a distant, one-dimensional evil sorceress, with little or no explanation given for her antagonism to the Round Table. In this case, Morgaine is presented as a woman with unique gifts and responsibilities at a time of enormous political and spiritual upheaval who is called upon to defend her indigenous heritage against impossible odds. The story is told in four large parts: "Book One: Mistress of Magic", "Book Two: The High Queen", "Book Three: The King Stag", and "Book Four: The Prisoner in the Oak". The novel was a best-seller upon its publication and remains popular to this day. Bradley and Diana L. Paxson later expanded the book into the Avalon series.
