Joe Pitt, a private investigator in a world of vampires, is a marked man after exposing a secret blood source, forcing him into hiding in the city's underbelly. For a year, he has survived by preying on the vulnerable in the subway tunnels and sewers, while above ground a civil war among vampire clans escalates, threatening to expose their existence. His objective becomes finding a missing girl carrying a child prophesied to be crucial to the future of vampire-kind, a task he undertakes only because his ex-girlfriend, Evie, asks him to. The narrative framework appears to be third-person, following Joe's gritty existence and his reluctant involvement in a conflict that could determine the fate of his world.

The premise sets up a dark, action-packed urban fantasy narrative with noir undertones, focusing on a protagonist in deep peril. The description suggests a high-stakes conflict driven by internal vampire politics and a potentially world-altering prophecy. The narrative appears to prioritize gritty realism within its supernatural context, with a focus on the protagonist's struggle for survival and his reluctant engagement with larger forces. The inclusion of a missing person case with profound implications hints at a complex plot that will likely involve investigation and confrontation.
