A tarnished saint and a polished devil sweep several ordinary people into a struggle for the holy grail, winner take the future.
When Maggie Sinclair walks into myth-haunted Glastonbury Abbey, she intends only to teach a group of students the stories of King Arthur. But she can't escape her mid-life crisis, which soon leads her to answer a spiritual call to arms that will change her world forever.
Maggie's student Rose Kildare is looking for romance and adventure. What she finds is murder and a crisis of faith. In searching for his missing father, a young Scot named Mick Dewar finds not only Rose, but his family's long-lost identity. And Ellen Sparrow thinks she's already found certainty but instead loses almost everything.
Over them all looms Robin Fitzroy. In the eleventh century he was Robert the Devil, father of William the Conqueror. Now immortal, secure in his pride, he serves Lucifer himself. Only Thomas Beckett, the great English saint, knows who Robin really is. Thomas let another man be martyred in his place in 1170. Since then he's lived as a humble scholar, seeking redemption for his sin. But now, at the end of time, he discovers that it's up to him to save the souls of mankind from Robin's clutches. He risks making allies of Maggie, Rose and Mick, even as he wonders whether not only his scholarship but his character is strong enough to meet the challenge.
