In a city of glass, law is literal—rituals and written oaths seal identity, and municipal power runs on the names it consumes. Mara Kestrel‑Voss is a liminal operative who trades in shadows and loopholes: a thief of forgotten permits, a reader of municipal arteries. When a rumor of an erasure-hinge colliding with a child's ledger surfaces, she and a fractious cadre of allies race beneath the streets to confront Seraphine Kade, the architect of the Remnant Lattice. What begins as a hunt for a mutable map becomes a desperate contest over language itself: statutes that wear masks, markets that auction erased lives, and a clause-foundry that will accept nothing less than a true name. Mara must braid a counter-oath from stolen echoes, bargain with orphaned jurisdictions, and choose which erased lives to save—while guarding the one thing she cannot surrender: who she once was. Ledger of Lost Names is a ritual-noir thriller about surveillance and sovereignty, the ethics of memory, and the costs of reclaiming identity from a city that profits by forgetting.
