What most people call a hellish shift, Josh Caplan calls a normal evening. After all, he works nights at a convenience store beside the mouth of hell, selling snacks to zombies and lizard men.

Some monsters are odder — and more dangerous — than most. Like the rampaging, oversized mustache who skips the Pringles and eats the customers instead. Or Cthulhu's half-brother Stan, who doesn't know how to take no for an answer…or where to put all those tentacles.

But killer facial hair and inept hentai beasts pale in comparison to the monster even other monsters fear. When hell's big boss demands a sit-down with Josh, she reveals a destiny bigger than he'd ever imagined — or wanted. You'd think preventing the apocalypse would net Josh more than minimum wage and a hot vampire boyfriend, but it turns out saving the world can be a pretty thankless job.
