Retributor (Hellgate, Montana Book 2‪)‬

Retributor Jeremiah Brandt has already riled up the zombie cavalry and he's still angry over losing a huge bounty on a clan of serial killers. So when the Helena Cattlemen's Association asks for help with a werewolf he jumps at the chance to take it on.

There are a few little kinks to work through first before he can get down to the hunt–starting with zombies, a revengeful sister, and cold bath water. But the hunter soon becomes the hunted as Brandt discovers that his past mistakes have come back haunt him.
