Rust gospel

The city buried its sins beneath rust and concrete.

Detective Arthur Finch has spent eight years trying to forget the disaster that destroyed his partner and buried the truth beneath corporate secrecy. When a nurse is found ritualistically murdered in the flooded undercity, marked with a symbol Arthur hasn't seen since the day twelve people died in the infamous Tolliver Spire incident, old ghosts come clawing back.

His investigation leads to the Halcyon Clarity Foundation, a growing movement promising freedom from grief, fear, and pain. Led by the brilliant and terrifying Mara Ilyenko—the disgraced scientist Arthur believes responsible for the worst tragedy of his career—the Foundation offers hope to a city drowning in despair.

But hope comes with a price.

As disappearances mount and volunteers emerge changed by secret "listening sessions," Arthur and his partner, Priya Okonkwo-Saint, uncover a conspiracy that blurs the line between technology, faith, and madness. Whatever Mara discovered eight years ago didn't die at Tolliver Spire.

It evolved.

Now Arthur must descend into the rusted heart of New Halcyon before a new gospel spreads—one that promises salvation by erasing what makes us human.
