Vesper of Pale Lights

As a rogue, unstoppable wave of architectural nanites silently crystallizes the Jovian habitats into inert light-sculptures, humanity's time in the outer solar system comes to an end. Amidst the slow, beautiful apocalypse, three orbital caretakers—an structural architect, a deep-trench haul pilot, and an ecological curator—must race against the encroaching tide. Bound by duty and their own deadpan domestic banter, they desperately ferry the last remnants of human culture and botanical life ahead of the transformation. But as the crystalline infection leaps from station to station, they face the agonizing choice of what to save, what to leave behind, and what it truly means to preserve a legacy in a dying system.
