A city on top of a Hellmouth. A war between pyromancers and incendiaries. A race against time to stop a demonic arsonist. Welcome to Perdition Falls, New York: where arson is considered a recreational activity, the abnormally hot climate makes everything unbearable, and according to one origin story shrouded in myth and legend, our city is an actual Hellmouth. When an incendiary—the name other pyromancers have given to the infestation of Hellfire-wielding demons—kills my closest friend and fellow firefighter, I’m left with a rare power I barely understand. It’s the only reason I survived. It also makes me a target. While a demonic arsonist puts the city’s resident pyromancers on edge, I’m reunited with my long-lost childhood friend Javier, who shares the same strange power that runs through my veins. We're the last defense against the incendiaries’ corrupt hold on the city…one completely disastrous mission at a time. But taking down this homicidal demon with a flair for pyromania might mean trusting one of their own.
