Merlin's Legacy-Daughter of Light

Cassandra of Tregaron possesses a strange and mystical power--a gift of prophecy that allows her to move freely through time and space. She is the third daughter of Merlin, fabled sorcerer and friend to King Arthur. Blue-eyed, beaufitul, and deeply lonely, she heals the sick in the hills at the edge of Avalon. Long ago she shunned the legacy that is her birthright and that she alone can claim.
Stephen of Valois is a true son of William the Converer and a valiant knight who must prove himself in battle by defeating the warlord, Malagraine. He encounters a luminous vision of a woman in flowing blue robes and cannot know that she will be come his destiny--and his only desire.
Drawn together on a quest that takes them to the crumbling ruins of an enchanted realm, Stephen and Cassandra must overcome the forces of darkness that threaten the mortal world--for a love stronger than Excalibur, more powerful than the Holy Grail...and everlasting as time itself.
