On the trail of a serial killer, vampire Quentin Albermarle is mistaken for the killer by a police special task force. Once the smoke clears, Quentin finds himself in a delicious position-atop one of the unit's crack officers, Darcy Henry. In need of Quentin's access to the vampire sub-culture, the task force leadership invites Quentin to join the crime unit as a special advisor, much to the chagrin of the men in the unit, and especially, of Darcy. A no-nonsense cop with no time for romance, Darcy suddenly finds herself embroiled in a steamy love triangle between her mortal partner, Joe, and the handsome vampire. Going from abstinence to wantonness, she is unable to resist the two men's relentless seduction or her own sensual curiosity about a vampire's special kiss. When the real killer threatens the life of someone close to her, Darcy makes a choice that forever binds the three of them together.
