The Nadir Chronicles

They bought humanity a thousand years of summer. Then the bill came due.

The Solari were not gods. They were the ignition switch. They burned a finite cosmic fuel called Luma to build a perfect childhood for the species: no hunger, no war, no early graves. When the math turned against them, they chose to die rather than become the thing that would eat their heirs.

Four centuries later the sky is a subscription.

Lucian Graves is a scavenger in the Nadir, the frozen undercity bolted to the corpse of paradise. He flies without a neural jack. He opens dead Solari doors with a pry bar. He owes a crime syndicate more money than he has thumbs, and his sister Kalia is drowning in Ash-Lung, the dust disease the landlords treat as a sorting hat.

Overseer Kael of the Vane Directorate buys that debt for a reason. A comet is coming through the sector. The Vane say it is a rock full of leftover light. Their computers cannot fly the debris around it because the universe itself has slipped off pitch, from a clean 400 hertz down toward 396. They need an analog pilot. They need Lucian.

What waits inside the ice is not a rock. It is a Seed-Ship the dead left behind, a house the living can read and cannot repair. Catch it and the last bridge between Earth and Mars might hold. Miss it and four hundred million people go dark. Turn it on and Lucian will find out what the Solari really spent, what the Vane have been rationing, and how expensive a childhood can be once winter starts.

The Glass Debt is Book One of The Nadir Chronicles, a post-utopian science fiction series about analog hands in a world that sold its sky.
