Meet the houseguest from hell! Geeky, squeaky-clean Max Kilgore has only one habit: digging for fossils. One day, to his horror, his shovel strikes not a dinosaur bone, but a pit to hell – and out of it comes a devil. Specifically, the kind of devil who gorges on junk food, watches a ton of reality television, plays violent video games, and refuses to leave Max’s basement. But evil is still evil, no matter what form it takes. And Max has to comply with the demands of the big red menace, lest he lay waste to everyone and everything Max cares about. With the help of Lore, a former Goth girl who knows a thing or two about the dark side, Max goes in search of a new abode for his unwanted guest. Finding a place where he can reside in Luciferian luxury isn’t easy, but Max has strong motivation: his mother, whose terminal illness the devil promises to cure if Max gives him what he wants. And pretty soon, Max is doing things the good kid he once was would never dream of doing. Clearly, hanging around with a devil is a bad influence. But how can Max get rid of the guy without incurring the wrath of hell?
