MudMan

Levi Adams is a soft spoken, middle-aged Mennonite man-at least he tries to be when he's not murdering people.Levi's a golem, a Mudman, crafted from the muck, mire, and corpses of a World War II concentration camp-killing is just a part of his DNA. He doesn't like it, but unfortunately he's been saddled with a divine commission to dole out judgment on those who shed innocent blood. After seventy years as a cold-blooded murder machine, however, Levi's trying to change his grisly nature. And the AA meetings and church services are helping. A little. But when he runs across a wounded girl, Sally Ryder, during one of his "hunting expeditions," he realizes self-help may have to go on the back burner.
Someone is attempting to revive a pre-Babylonian murder god, and the road to rebirth is paved with dead bodies. Lots and lots of them.
Now, Levi must protect Ryder-the key to an unspeakable resurrection-and defeat a Nazi mage from Levi's murky past. But the shadowy mage holds a terrible secret about the Mudman's unorthodox birth, one offering insight into Levi's morbid compulsion for bloodshed. It's a secret Levi would pay anything to uncover: maybe even Ryder's life. If Levi isn't careful, he may end up turning into the monster he always imagined himself to be.
"Levi Adams isn't good in social settings, but he's great at killing things. A dark tale of vengeance and redemption (with a healthy dose of ass kicking), James Hunter's MudMan is a knockdown beat-'em-up that doesn't pull any punches." -Domino Finn, author of the Black Magic Outlaw series
