A city without a name is summoned to finish its sentence.
Amara Selene and Kiran Hayes cross the Sea of Indices to argue before the Serifs, where punctuation decides nations and a single stroke can file a world forever. The Trustees push a "Safety Address" built from stolen minutes. Attention itself takes the stand. C is licensed to signal but never lead. To keep their people unfiled, Amara must surrender her perfect pitch, Kiran must walk the Proof Scriptorium, and together they must open a forgetting corridor under oath-no one lost, no address signature left behind.
Kerr sponsors a painless shadow to replace human ache. The Serifs demand two signatures or a lawful dot that will hold the semicolon open-at the risk of neighborhoods fading. When a True-Name Engine powers up over the city, Kiran draws the shear across its reflection and the chamber inhales.
Doctrine of Attention is Book Five in Eclipse of Worlds-brooding hard sci-fi with legal-linguistic magic, civic resistance, and cosmic witness.
