2002’s The Disappeared is the first volume in Kristine Kathryn Rusch’s Retrieval Artist series.
Faster-than-light travel gave humans the stars and contact with other intelligent species. Each alien civilization has its own set of laws. The question of whose laws apply when and to whom is the subject of carefully negotiated treaties. Those treaties complicate the lives of hard-working space cops.
Miles Flint and Noelle DeRicci enforce the law in the Moon’s Armstrong Dome. Armstrong has a starport, which means that alien entanglements are always a possibility. Still, treaty complications aren’t exactly common, which is why it is so odd when Flint and DeRicci are faced with three such cases at the same time.
