Dead Red — M.R. Forbes

Conor Night, the world's only surviving necromancer, is used to having bad days. After all, he's spent the last few years as a minor pawn in the Game of Houses while keeping one foot planted firmly in the grave. But between the job offer he can't refuse from a wizard he doesn't trust, and the appearance of a cult bent on sending him to the afterlife, his days are about to get a whole lot worse. He's used to the threat of death. Death making threats? That's new.
