In the midst of life, there is death. In the hustle and bustle of London society, Sarah Ashton is being watched by a man who has known both life and death -- and gone beyond them to the endless existence of the undead. There is much for this mysterious watcher to admire about the gently-born young lady: her beauty, her intelligence -- and the alluring flow of her blood, pulsing at temple and wrist and throat. At first, Sarah has no idea that the man she knows as Davinoff is more than just a darkly handsome foreign nobleman. But when she realizes her admirer is a supernatural being, more than just her life is in danger. For, while the passionate sacrament Davinoff desires demands both her life and her love for all eternity, there are those among the dark ones who would fight to claim her very soul.
