The Last Enchantment

Arthur Pendragon is king! Crowned and recognized as High King, Arthur is unchallenged on the battlefield, and he melds the country together in a time of promise, as Merlin works in the shadows.
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.
"The richest of the three…mighty…climactic…action and suspense constant, even harrowing."
"A perfect trip out of the present."
"An absorbing and haunting novel."
"A fascinating novel, a richly woven tapestry presented with a vividness that brings the characters from myth to real life."
"Narrator Derek Perkins employs a conversational tone in this new production of the third book in Stewart's renowned Arthurian saga…Perkins illuminates the evolving role of Merlin as teacher, prophet, and advisor to Arthur in their dialogue…As Merlin ruminates upon events in his own life and his waning powers, Perkins adopts a reflective attitude tinged with sadness as well as full confidence that his apprentice will serve Arthur faithfully."
