Aleric: Monster Hunter

Aleric Toma Bimbai is a two-hundred-year-old Rom, Gypsy, and a legend among his people. He hunts monsters for bounty, a gun for hire, with secrets as dark as midnight in a graveyard. He is a hero and rogue rolled into one, with preternatural powers of his own, only slightly better than the supernatural creatures he hunts. His exploits border on the mythical and the legendary. His is a land where good versus evil in a never-ending battle for supremacy, and in his world a very thin line separates the two.
He walks that line every night. He is in a constant struggle to remain on the side of good, but he must often cross over to the side of evil and meet his adversaries on their ground. Defeat is not an option. He is a hero who believes that the end does justify the means, and he will do whatever it takes to win and to stay alive to fight another day. To that end there is a price to pay. But he pays it willingly, sacrificing eternal salvation for his own soul to help make the world better for all.
Aleric's task this time is to save a zombie rather than exterminate it. But Wasso Wonko is no ordinary zombie. He's different. He can still think. He can talk. Besides, Wasso is also Gypsy. Aleric soon uncovers an immoral alliance between local doctor, Wilhelm Ratterman, and the self-proclaimed King of the Gypsies, Carranza Tene. Tene is supplying his own people as guinea pigs for Ratterman's bizarre experiments.
Ratterman is in search of a serum that will not only give him strength and courage but also immortality. But he's foolishly using the zombie virus as a catalyst in his serum. Under the guise of free flu shots, the doctor's testing that undeadly serum on the Gypsies that King Tene supplies him. Is there an antidote? If so, can Aleric find it in time to save Wasso from his undead existence? To complicate matters, Wasso goes missing.
Ratterman's serum-a Molotov cocktail of chemicals, zombie virus, and now vampire blood-succeeds only in regressing the doctor back through evolution, transforming him into a rampaging, primitive beast-a Neanderthal. King Tene puts a contract out on Aleric's head. Pearsa, Aleric's new girlfriend and boojo woman is running a scam on an old woman, and both she and her mark go missing. Aleric believes that Jeta, his two-hundred-year-old vampire wife, targeted Pearsa in a fit of jealous rage.
What's worse, Jeta's vampire lover, Kinski, is set on ripping out Aleric's heart-you don't want to get vampires jealous. Aleric must find the antidote if it exists. He must now track down both Wasso and the Neanderthal. One, he must save. The other, he must destroy. Pearsa's life also depends on him finding her. But he must save her without harming Jeta in the process, for he and his vampire bride have a relationship that is not only long and dark but twisted and complicated.
And to succeed, Aleric must fight his way through King Tene's Gypsy henchmen, an assassin bent on collecting a high-priced fee, and the pissed-off vampire Kinski. To succeed he must simply stay alive, for he is the world's best hope and last line of defense against evil. He is Aleric: Monster Hunter.
