Relentless — Delilah Devlin

To supercop Max Weir, the only good vampire is a dead one. Since his special police unit integrated with vampires, he's had to suppress his natural hatred to work side-by-side with the undead to hunt down and terminate the deadliest killers. Now the unit is hot on the trail of a new menace in town, a pack of werewolves prowling for vampires, who don't care whether humans get in their way.

When a stakeout goes awry, Max enters a bar looking for a fight or a woman to help him blow off a little steam. What he finds is a winsome siren who has sexual appetites to match his own.

Vampire Pia D'Amato is on a secret mission to take out Max -- either by seduction or by turning him. He's become a liability to the Masters' Council setting up jurisdiction in southern Florida, and she isn't leaving until she's done the job. But Max is more man than she bargained for and has a deadly secret of his own.
