The Richmond Vampire

Mack's a vampire hunter, Bellafleure's a vampire, and together they have to find a serial killer before he strikes again. It's a classic case of "opposites distract".  Mack is a B-grade vampire hunter, a beat cops who does his best to keep the streets of New Orleans safe from the things that go bump in the night. Mack's family has clout in the vampire hunter community, so he and his partner get sent to Richmond to track down the serial killer who's leaving dead bodies in a cemetery.
And they damned well better find him before he strikes again. As soon as their boots hit the ground, Adrian Bellafleure - the Richmond Vampire - offers his help. Trusting a vampire goes against everything Mack has ever learned, but he's practical enough to grudgingly accept the offer. Bellafleure has a new vision for vampires and the people who hunt them, and if they can catch the bad guy, Mack might give him a listen.
Because yeah, that vampire's just about the hottest guy Mack has met in a good long while, and his dick is ready to ignore a lifetime of training. For that matter, so is his heart.
