It's been a hell of a day for Abby Barlow. In just a few hours, she's survived an explosion, watched her employer die, had a startling dream, and now she finds herself in a seedy Chicago hotel with the sexy, unearthly Dante, a man she both desires and fears. For three hundred and forty-one years, Dante has stood as guardian to The Chalice, a mortal woman chosen to hold back the darkness. A terrible twist of fate has now made Abby that woman. Three hours ago, Dante would have used all his charms to seduce her. Now she is his to protect. And he will do so until his very death. A terrifying plan has been set in motion, one that will plunge Dante and Abby into an epic battle between good and evil—and a desperate race to save their love.
