In Silvergate, where neon barely masks the grime, Detective James Black thought he'd seen it all. Then the bodies started to appear, each with ancient symbols carved into their flesh. As the corpses multiply, each more horrifically mutilated than the last, Black realizes he's hunting a killer who believes they're on a holy mission.

The cryptic runes left at each scene mock Black's efforts, hinting at motives rooted in forgotten history and occult obsession. When the case turns brutally personal, Black's investigation plunges him into Silvergate's darkest corners, where deadly secrets lurk beneath the surface.

As citywide panic erupts in violent riots, Black races to decipher the killer's twisted logic. But the deeper he digs, the more he questions everything he thought he knew - about the city, about himself, and about the thin line between sanity and madness.

With a killer always one step ahead and his list of allies shrinking, Black must confront the darkness in his own past to have any hope of stopping the slaughter. In a city unprepared for such savagery, he'll be forced to decide how much of his humanity he's willing to sacrifice in the name of justice.

"The Rune Killer" - Where ancient brutality collides with modern justice, and one detective's obsession could unleash forces that will shatter reality itself.
