The mountain air kills. The dome decides who breathes.
When a mysterious atmospheric event turns a remote mountain region into a dead zone, the experimental town of Halcyon becomes the last place where clean air still exists. Beneath its white oxygen dome, families sleep beside condensation-slick walls, sirens measure every breath, and survival depends on a system no one is allowed to question.
Mara Chen, a disaster logistics specialist haunted by the evacuation she once failed to complete, arrives with one mandate: stabilize Halcyon and move its people out before the oxygen reserves collapse in seventy-two hours. But the town is already dividing itself. The upper sectors receive clean air. The lower sectors receive delays, denials, and locked doors.
Then residents begin vanishing.
An engineer insists he built the dome to save lives, not rank them. A corporate medical director calls the deaths "necessary triage." A teacher hides children in an illegal shelter. And a teenage hacker claims the ventilation system is whispering back.
As Mara follows the missing into the filtration tunnels beneath Halcyon, she discovers the terrifying truth: the dome may not be protecting the town from the poisoned world outside. It may be keeping something alive within.
Cold, atmospheric, and morally ruthless, The Last Oxygen Town is a survival thriller about scarcity, corporate power, and the question inside every disaster: when there is not enough air for everyone, who decides who lives?
