The novel explores the eerie and supernatural as it follows the life of a recovering alcoholic and writer in San Francisco who becomes entangled in a web of occult horror. After discovering a mysterious book, he is drawn into the world of "paramentals"—sinister entities that feed on the energy of the modern city—and must confront the legacy of a long-dead sorcerer. As the protagonist delves deeper into the arcane, he must unravel the secrets of an ancient mystical theory called Megapolisomancy and face the terrifying forces that lurk in the shadows of urban decay, all while grappling with his personal demons.
