Enemy of God
by Bernard Cornwell
Arthur, still defending Britain for his younger half-brother Mordred, faces religious uprisings, Saxon invasions, and disloyalty at the heart of the kingdom. His uncompromising belief in oaths and his optimistic blindness to human betrayal isolate him from even his closest friends. At the same time, Merlin's quest for the Cauldron (or Holy Grail) also becomes entangled in treachery.

Mists of Avalon
by Marion Zimmer Bradley
The Mists of Avalon is a legendary saga of King Arthur and his companions at Camelot, their battles, love, and devotion, told this time from the perspective of the women involved. Viviane is "The Lady of the Lake," the magical priestess of the Isle of Avalon, a special mist-shrouded place which becomes more difficult to reach as people turn away from its nature- and Goddess-oriented religion. Viviane's quest is to find a king who will be loyal to Avalon as well as to Christianity.

The Return of Merlin
by Deepak Chopra
In The Return of Merlin, Deepak Chopra proves a born storyteller. Although a book of incandescent fiction, The Return of Merlin is rich with the spiritual themes identified with Deepak Chopra: the hidden possibilities of wonder in the everyday world, the peace that lies behind the infinite masks of change, and the miraculous transformations made possible by shifts of perception. The message Merlin delivers is that "we can dream a new world from the purity of our own hearts." The rebirth of Camelot becomes vision and prophecy.

The Winter King
by Bernard Cornwell
Cornwell interweaves elements of history, mysticism, and folklore, spinning a fantastic revision of the standard Arthurian legend. In this version, Arthur, the bastard son of Uther, pledges his fidelity and protection to his infant nephew, Mordred, the rightful heir to the Kingdom of Dumnonia. In a Britain populated by both druids and Christians, torn asunder by feuding regional factions, and threatened by invading Saxons, Arthur emerges as a powerful, courageous warlord capable of inspiring loyalty and healing festering wounds.
