What do you leave at a lost-and-found for things not yet lost?
Silas Bell runs an impossible shop on Bellwether Street. People bring him the objects they fear losing before loss arrives: wedding rings before marriages break, keys before doors close, letters before courage fails. Silas gives each object a number, a return condition, and a safe place to wait. If loss can be given a procedure, perhaps it can be survived.
At least, that is the theory.
Then seventeen-year-old Niko secretly films the shop. His video transforms a quiet refuge for private sorrow into a public curiosity-and brings structural engineer Mara Venn to the door with news Silas cannot file away: the aging building, and the forgotten waterway beneath it, may not survive the next storm.
As rain gathers and the city's systems begin deciding who and what counts, Silas confronts the limits of his careful arithmetic. Protecting every object may endanger the people those objects were meant to serve. Preserving evidence of love is not the same as loving. And some losses cannot be prevented-only given meaning.
Beyond the visible world, a vast, argumentative Intelligence is watching. It believes every human choice can be reduced to probability. Silas Bell may be the remainder it cannot resolve.
Cosmic, darkly funny, and deeply human, The Dark Arithmetic of Stars is a literary speculative novel about grief, love, impossible inventories, and the meanings no universe can calculate for us.
