A Treaty for the Unborn. The Distance of Law, #2

The treaty is authentic. Everyone who signed it is dead. The people forced to honor it are still alive. The Shared Passage Compact once kept three distant habitats connected. It also bound workers, machines, and future officeholders to obligations they never accepted. Now the beam corridor is failing, its scheduled shutdown is approaching, and Common Measure needs that same corridor to survive its thirteen-year journey to Lattice Reach.
At Mercy, physicist Rhea Maddox builds a phase network in which local operators can refuse dangerous loads without surrendering rescue. Aboard Common Measure, her husband Julian endures sustained acceleration, a damaged body, and negotiations conducted through records that outlive the people who made them. Each reply arrives from an earlier officeholder. Each solution risks becoming the next inherited command.
When a source withdraws and an operator is injured, the final deceleration can succeed only if Tamarisk, Long Harbor, Mica, two arriving vessels, and the workers who carry the heat accept separate present-tense terms. No founder, mediator, spouse, or institution can answer for them. Across incompatible clocks, Rhea and Julian face a second question: whether a marriage can be renewed without turning an old promise into authority over the people they have become.
A Treaty for the Unborn is Book Two of The Distance of Law, a grounded hard-SF political thriller about rescue, labor, consent, and the future people asked to live inside agreements they never signed.
