The mists of time

the long version

"Divided by centuries, Diana Dearborn knows all about romance, at least in the books she writes. But passion eludes her in real life--until she's offered the chance to travel back in time to Camelot. The world of King Arthur and Guinevere is nothing like she pictured, and neither is the knight she encounters on her return to San Francisco: Gawain, the hero of her current project. He's complicated, mysterious, and sexier than anything her imagination could conjure. And he's been waiting for her. Entwined by desire, now, joined together in a desperate race, Diana and Gawain must prevent an ancient, evil force from wreaking mayhem in the all-too-real present."--P. [4] of cover.
