Oxygen Debt

OXYGEN DEBT: A Sci-Fi Survival Novella.

On Mars, every breath is engineered.

When a minor calibration error causes oxygen levels to dip inside the first human colony, systems engineer Dr. Lena Roen assumes it’s a routine fix. A decimal out of place. A curve slightly off tolerance. Nothing worth waking the commander over.

She’s wrong.

As oxygen production continues to fall, the colony faces an impossible truth: the failure isn’t mechanical—it’s cumulative. Small decisions. Quiet compromises. And a system designed to report stability long after survival becomes uncertain.

With panic rising and trust fracturing, Lena must race against time to correct a problem that may already be beyond repair. Every choice now carries weight.

Every delay costs air. And every solution forces a question no system was built to answer:

Who gets to breathe when there isn’t enough to go around?

Oxygen Debt is a tense, grounded science-fiction thriller about survival, responsibility, and the fragile math behind human life—perfect for listeners who enjoy realistic space disasters, ethical dilemmas, and high-stakes sci-fi in the vein of The Martian and Gravity.

Wonderful story of survival and adaptation

I loved this story and the narrator presented the story in an amazing way. The narrator crafted each voice and tone wonderfully. I would definitely recommend this book and read more of the author’s work. I would also listen to more book by this narrator.
