Absolution by Lissa Kasey

Sam is used to being the bad guy. So when he becomes the undead, he doesn’t understand why it pisses him off. Sure guys throw themselves at him, and he’s strong enough to toss a car across a room, but he’s friends with two of the four pillars of Dominion power and mentored by one of the most powerful vampires in the world. Things that put a damper on his whole ‘scourge of darkness’ vibe.

For months he’s been letting a little red-eyed monster out to play and feeding on the dangerous instead of on the willing. If it weren’t for his endless desire to take a nibble from his sexy and tattooed roommate, Constantine, he’d still be stalking the night looking for human monsters to devour. Instead he’s taking on a cibo, a regular blood donor, in the form of Luca, a dhampir.

With Luca and his profound knowledge of undead politics in his life, Sam begins to realize he doesn’t know as much as he thought, and maybe that’s not his fault. His mentor’s sanity is slipping, the world is changing, and vampires are beginning to lose control. Will Sam fall into the darkness too, or can Luca and Con drag him back from the abyss?
