About this book:

Dr. Elara Vance has twenty-four hours left on Oakhaven. One final shift at the Fringe Veterinary Station, then a transport ship to a core-world lab where the worst hazard is a paper cut. But the terraforming spires that make this brutal planet breathable have just begun to fail—and they're taking the atmosphere with them.

Trapped in a fortress clinic with twelve critical patients, a grumpy technician, and a planet tearing itself apart, Elara trades her exit strategy for a siege. Ion storms shred the sky. Pressure spikes stop hearts. The very animals she's sworn to protect—bio-engineered draft horses, mutant tortoises, an Arcturian fennec—are the first to sense the collapse. And the replacement doctor arriving tomorrow? He's walking into a death trap.

From the author of *The Last Shift at Fringe Veterinary Station* comes a white-knuckle fusion of veterinary medicine and planetary disaster. Where *The Martian* meets *All Creatures Great and Small*, this is frontier sci-fi at its most visceral: a healer's last stand on a world that never wanted us. The clock is ticking. The sky is turning green. And the night shift has only just begun.
