First Contact. The Orun Concordance, #1

Three worlds share an ancestor. They do not share a definition of proof. Sere records truth in fired ceramic and marks every claim by how it is known. Meral stores testimony as warmth in walls, where silence carries legal weight. Oruve controls the ships and patents connecting them. When a repeating rhythm appears in the gaps between routine engine transmissions, scattered technicians, archivists, kiln workers, clerks, and diplomats begin to notice the same impossible fact: the pattern may predate the first contact recognized by history.
Confirmation should unite the worlds. Instead, it exposes the fault lines between them. One civilization hears certainty where another hears aggression. A careful qualification becomes "perhaps" in translation. Unlicensed voices answer before governments can decide who has the right to speak. Markets move, berths close, and paperwork starts to resemble the weather of war. To prevent contact from becoming conflict, three civilizations must invent not just a common message, but a common way to take turns, preserve doubt, and let silence mean something other than refusal.
First Contact opens The Orun Concordance with a compact, mosaic-style work of hard social science fiction about evidence, language, institutions, and the politics of speaking for a world.
