Nine Princes of Blood (Vance Silver, Vampire, Hunter Book 1)

The last of the vampire hunters, Vance Silver seeks a legend to aid him in his mission to cleanse the world of the bloodsuckers. The trail has taken him to Los Angeles, but before he even settles in, the world of the night overwhelms him. Vampire society in southern California is especially chaotic and lacking leadership. A cohort of powerful vampires are maintaining anarchy in the city for their own deadly amusement. Vance's morality is tested and twisted as he tried to find footing in a world where he cannot even comprehend the mortal society. When he finds himself forced to ally with one vampire faction against another, he wonders if he'll ever be the man he thought he was meant to be. He'll face the ultimate test when the cost of his integrity will be murder. (Nine Princes of Blood and the rest of the series was previously the Nate Silver, Vampire, Hunter series. The books were revised, not republished)
