Ashfall Sanctuary

When the sky splits open over Denver and a blood-red System descends, every screen, windshield, and window becomes a countdown to extinction. In the first hour, the dead rise inside apartment blocks, subway tunnels flood with nest-spawned horrors, and entire neighborhoods are marked as contested zones where only the strong will keep breathing. Evan Mercer, a burned-out hospital security guard with a talent for staying calm in disasters, survives the opening massacre by sealing a trauma wing and making one impossible choice: he claims a forbidden class meant for wardens, jailers, and executioners.

The class brands him as something the new world was never meant to trust. To protect a handful of survivors, Evan must turn a ruined hospital into a fragile safe zone while monster waves hammer the walls, desperate refugees bring secrets and infection, and rival factions rise from police precincts, megachurch shelters, and corporate bunkers. But the System is not just testing humanity’s strength. Buried beneath the city lies an ancient prison waking under the ash, and Evan’s class key fits every lock. If Sanctuary falls, Denver becomes the first breach point in a war between Earth and everything chained below it.
