On the outside, Max is a normal office worker. He is stressed, overworked, and newly dumped, and now he has to train a classer to take the promotion he deserves. Max has neither the money nor connections to become a classer himself, at least not legally. Only the elite of the elite are permitted to access dungeons or to claim the classes they provide. Max's home holds a secret, however, one that will draw him into a world of intrigue and adventure. Will Max survive the dangers that lie beneath his backyard shed, or will they destroy him?
