The Last Line to Denver
A Post-Apocalyptic Infrastructure Novel

About this book:

The Trans-Continental Pneumatic System is the only artery keeping Denver alive—eleven hundred miles of buried alloy pipe, hurtling seeds, serum, and machine parts through vacuum at four hundred miles an hour. When the pressure drops, the capsules stall. When the capsules stall, the city starves. Chief Engineer Harlan Miller has spent twenty years coaxing life from rusted turbines, patching seals with mutton fat and desperation, and staring down scavengers who’d tear the line apart for a lungful of compressed air. But the metal is fatiguing, the spare parts are fictions, and something in the dark is learning how to hunt the Line.

From the wind-scoured cuts of eastern Colorado to the Mile-High vaults beneath the Rockies, *The Last Line to Denver* turns infrastructure into a heartbeat. This is post-apocalyptic fiction stripped of romance and replaced with torque specs, bearing clearances, and the grim calculus of men who know exactly how many PSI separate civilization from the dark. Every valve sealed, every turbine nursed past redline, every mile held is a victory bought in grease, lead, and the quiet competence that keeps the world turning.

Gritty, technically precise, and relentlessly paced, this is *The Martian* meets *The Road* for the heavy-industrial age—a novel where the hero carries a breaker bar instead of a blaster, and the most terrifying sound in the wasteland isn't a gunshot, but a needle sagging on a gauge. The Line is bleeding. The turbines are screaming. And Harlan Miller is running out of mutton fat.
