A woman dies in the domed city of Armstrong on the Moon. Detective Noelle DeRicci discovers that the victim is a Disappeared—an outlaw in hiding wanted for crimes against an alien civilization. Only DeRicci's old partner, Retrieval Artist Miles Flint brought the Disappeared home, something he would have only done if he believed the alien government would exonerate her for her crimes.

But Flint and DeRicci are no longer partners; in fact, they're on opposite sides of the law. Flint can't tell DeRicci about his client's role in a war between humans and a mysterious alien race. The Disappeared's death is only the first volley in an escalation of that war, a war that threatens to engulf the entire solar system.

International bestselling writer Kristine Kathryn Rusch has won two Hugo awards, a World Fantasy Award, and three Asimov's Readers Choice Awards. IO9 called her six (so far) bestselling, award-winning Retrieval Artist novels one of the top ten science fiction detective series ever.
