A Choir of Unmade Worlds

About this book

Umbra-9 runs on futures that never happened. Every midnight, its canyon streets and rooms quietly rearrange according to probability forecasts, and citizens carry continuity ledgers so municipal cartographers can certify what is still real. Sera Vey certifies. She is precise, patient, and cannot recognize a face — she knows people by voice, by gait, by the shape of the space they disturb. Summoned to a sealed observatory, she finds astronomer Jalen Or murdered behind a door no person could have opened. The trouble is that Jalen is alive across the city, arguing his own case. Six districts each remember the killing differently, and each memory holds together perfectly. In the dead man's marrow lies a map of stars that never formed. Sera's job is to decide which version of that night the city will call true — before something on the other side of the map decides for her.
