Kepler Station is dying. The air is thin. The lights are failing. And the council has quietly decided to let it rot. Systems engineer Mara Voss has spent eleven months keeping this outer-colony station alive on stubbornness alone — crawling through conduits, filing reports nobody reads, patching failures nobody funds. She has never been afraid of anything she could diagnose. Then she finds the roots. Thick as her forearm. Warm. Bioluminescent. Threaded through the station's infrastructure with the patience of something that has been growing in the dark for thirty years. Her scanner returns a result she has never seen: BIOLOGICAL COMPLEXITY EXCEEDS ANALYSIS PARAMETERS. And the roots lean toward her light. What Mara has found is the Verdant Engine — a living biogenesis system buried and suppressed by the station's council, built by a brilliant scientist who died alone in a sealed laboratory believing no one would ever find her work in time. She was wrong. Now Mara has sixty-eight hours before a demolition order erases everything. She has a botanist who weeps at the sight of species he thought were extinct. A security chief who has been guarding a secret door for thirty years. An archivist with a founding charter hidden in a maintenance locker. And a living system growing through the station's walls that may be the last blueprint for survival humanity has left. The Verdant Engine does not just grow things. It repairs hull fractures in vacuum. It seals failing recyclers. It produces oxygen calibrated to the number of people breathing it. Dr. Ilara Sonn did not build a garden. She built the immune system for a dying world. And it has been waiting thirty-one years for the right person to find it. Book 1 of The Verdant Engine Series. For readers of James S.A. Corey, Becky Chambers, and Ann Leckie. The engine was never meant to run on one station.
