There are things underground you would not believe. Disgraced anthropology professor Jim Murray has been drawn into the dark. Ousted from his career by the algorithm and mob rule, desperate for money, he joins a shabby crew of repairmen working in the tunnels beneath the City of Detroit. They say their job is to keep the earth from falling in. One day, waist-deep in the filth, they stumble upon an ancient secret and soon discover that the city above them is no longer home. In time, the sewer will show Jim worlds far stranger: a landscape scourged by fire and insanity, a dystopia ruled by a mad god...To find his way through the labyrinth will prove to be a brutal test of his soul—and a penetration into the nature of reality. File under: literary psy-fi, blue collar cosmic horror, McCarthyian Weird Fiction, Borgesian thriller, the good stuff.
