(Harper Voyager, May 6, 2003)
Arthur Pendragon is King! Unchallenged on the battlefield, he melds the country together in a time of promise. But sinister powers plot to destroy Camelot, and when the witch-queen Morgause - Arthur's own half sister - ensnares him in an incestuous liaison, a fatal web of love, betrayal, and bloody vengeance is woven.
