The Oxygen Farmer of Luna
A Moon Colony Mystery

About this book:

On Luna, every breath is a harvest—and twelve-year-old Mira knows the fungal vats of Bio-Dome 4 better than anyone. She tends the glowing *Cladosporium* that scrubs carbon dioxide and exhales oxygen for three thousand colonists, reading the crops' health in their bioluminescent pulse: turquoise for calm, emerald for hunger, violet for stress. But at midnight, Vat 19 blooms a fierce, geometric orange, tracing sharp right angles across ten meters of mycelium. It isn't a chemical glitch. It's a message. And it points straight to Sector 4—an "unexcavated" basalt block the colony maps insist is solid rock.

With her father exhausted by quota battles and the Colony Board burying anomalies, Mira teams up with Jonah, a comms-tech's son who's tracked a phantom power draw in the same forbidden sector. Together they uncover a hidden sub-level, a sabotaged recycler, and a conspiracy that could suffocate the entire habitat. Pursued by administrators who'd rather silence questions than fix leaks, Mira must decipher the fungi's code before the air runs thin—because on the Moon, the truth doesn't just set you free. It keeps you breathing.

*The Oxygen Farmer of Luna* is a taut, atmospheric mystery set in a vividly realized lunar colony where biology is engineering, silence is suspicious, and a girl who listens to glowing mushrooms may be the only one who hears the colony crying for help.
