Echea — Kristine Kathryn Rusch

Sarah thinks she has the perfect family. She and her husband decide to share that perfection with Echea, an orphan from the Moon Wars. But after Sarah adopts Echea, she realizes that Echea has problems. Serious problems. Problems that might change Sarah's entire family. Forever.

A hauntingly unforgettable story about the choices parents must make for their children, “Echea” won the Asimov's and Homer Readers' Choice Awards and placed as a finalist for the Hugo, Nebula, Sturgeon, and Locus awards.

“One of the five best stories of the year.”
