Paul Lewis, a talented young artist, is haunted by visions of a vampire.

Paul is commissioned to illustrate a manuscript of the gospels at San Benedetto monastery, where he meets Brother Victor. He falls hard for the bold and arrogant brother, unaware that Victor is the vampire of his visions, a ruthless killer and Jesus’s former lover.

Victor initially resists his own attraction to Paul, but he is forced to make a choice when Paul witnesses Victor murder a monk: destroy Paul, or turn him into a thrall—a half-human, half-vampire creature completely dependent upon his creator. Unable to destroy him, Victor chooses the only other option.

Now it’s Paul’s turn to choose: remain Victor’s thrall or become a full vampire, knowing to become a vampire will release Victor from the realm of the living forever. But Paul’s visions are back, and they’re urging him to turn against the vampire he loves. Can Victor crush this power and conquer Paul before it’s too late?
