Living Hell - Caitlin Yarsky

Jerome is determined to stay out of trouble, but when he kills one of Hell''s most vicious bounty hunters in self-defense, he inherits the job of infernal bailiff, hunting down his own kind. Jerome soon faces a range of ancient deities and monsters, from the human-eating ghosts known as Jikininki to psychopomps like Baron Samedi. But with every act of betrayal, Jerome loses a little more of his hard-earned humanity.
