The Breathing Class
In the perfect city on Mars, the air you receive depends on who you are.
Dr Eirik Halvorsen has been hired to certify Continuity One before its next expansion. Then he finds an empty scrubber cradle where a life-support core is recorded as installed. One discrepancy becomes a pattern: oxygen counted twice, shelter renamed until it shelters no one, and a survival model that has already decided which people can disappear from the denominator.
The Oxygen Debt
Leverage. Air rank is exposed as inherited entitlement. A worker-civic council must dismantle the regime without becoming the next office that decides whose emergency matters.
The Sovereign Orbit
Authority. Mars has a paper claim to self-government and no control over the ships, depots, fuel, traffic, or communications that make sovereignty physical.
The Last Window
Verdict. Earth, Moon, and Mars enter one final transfer crisis. The old road cannot remain sovereign, but the worlds still need a road when it is gone.
Reader contract
Hard science with people inside it.
The engines obey physics. The settlements obey logistics. The institutions obey incentives. No sentient machine creates the danger, no miracle technology erases scarcity, and no single leak fixes civilisation.
The series is pro-engineering, pro-competence, and deeply suspicious of any system that converts survival into a privately governed claim.
