The Cracks That Remember

The Martian colony of Dawnline has seven days before a catastrophic sandstorm destroys its life-support systems. When maintenance apprentice Lin Li discovers that the cracks in a rover wheel form distress coordinates sent from the future, she also uncovers a terrifying rule: every fracture she repairs causes the colony to forget one resident. To find a rumored underground refuge, she must lead a doctor, an archivist, a miner, a security officer, and a child with no verifiable identity through the sealed city—while exposing eighteen years of manipulated records and stolen memories. Are the cracks a warning, a trap, or the last testimony of those already erased?
