No Command Survives the Distance. The Distance of Law, #3

Eleven systems begin to fail on eleven local clocks. Any command meant to save them will arrive already old. The order outlived the war. The treaty outlived its signers. Now the infrastructure meant to replace both is failing. At Mercy, warnings from eleven connected systems arrive close enough together to look simultaneous. Their true origins are years apart. Optical references have aged under different radiation, heat, repair, and labor histories, leaving each community with a different physical problem by the time any answer can reach it.
Officials want physicist Rhea Maddox to sign one universal stabilization command. It would be clean, fast-and false. Across 11.224 light-years, Julian Maddox has already begun the return aboard Common Measure. The passage will consume more than sixteen years in Mercy's frame and less than eleven for him. Every acceleration and braking act depends on current workers he cannot command. Every message from Rhea carries a woman younger than the one who receives his answer.
If the route holds, they will meet again separated by more than a decade of age. Then a dust strike kills two people, a critical emitter line goes dark, and a refugee carrier enters the same narrowing rescue margin. Central authority offers the speed of a single answer. Survival requires something harder: evidence that remains dated, risks that remain named, and separate people free to accept, refuse, revise, or walk away.
Rhea must surrender the standing others keep trying to restore around her. Julian must return as a passenger and husband, not a claim on the woman whose life continued beyond his departure. Neither can preserve a system-or a marriage-by pretending distance did not change the people inside it. No Command Survives the Distance is Book Three of The Distance of Law, a grounded hard-SF political thriller about delayed truth, skilled labor, distributed rescue, disability, aging, and love that must be chosen in the present tense.
