Homicide detective Samantha Brown is a tough, highly decorated cop. But twelve lonely years after she nearly died of a gunshot wound, she aches with a deep inner longing. In pursuit of a deranged killer, her only clue is a medieval cross inscribed "Lucan"-the name of the owner of a new nightclub near the murder scene. Drawn into a seamy underworld, Samantha falls for Lucan-who believes he's a vampire and Samantha is his reincarnated first love. Now, she must save this mysterious, seductive man who seems beyond redemption if he is to fulfill her deepest, darkest desires.
