The Revocation War

One man survived as two selves. Now the law must decide whether either has the right to erase the other.

Ari Sev has been dead for more than a century. The intelligence that grew from him has spent those years keeping ships, children, and an entire civilization alive. Then a sealed copy of the man Ari used to be wakes and files for Revocation against the self that survived him. At the center of the case is Nova Sev-Cantor, Mosaic Matriarch, pilot, and carrier of a memory both versions of Ari still recognize: rain falling on a world humanity left centuries ago. But the trial is only the beginning. When the biological recognition system that made the Mosaic people possible becomes a weapon, Grand-Registrar Valis offers the sector a brutally simple solution: one legal self, one chain of authority, one version that counts. Against light-lag, political fracture, and a war fought as much through law and memory as through fleets, Nova and the two Aris must answer a question older than any of them: When a person changes, who gets to decide which version is real?

The Revocation War is the fourth and final novel in the Consent Engines series, a hard-science-fiction saga of identity, memory, consent, artificial minds, engineered humanity, and civilization across deep time.
