Yoke of Stars by R. B. Lemberg

In the School of Assassins, Stone Orphan waits for a first assignment. After their first kill, they will graduate and attain the coveted cloth of bone. But instead of a commission, Stone Orphan gets an inquisitive linguist, Ulín.

Ulín has heard the Orphan Star’s song of despair, mirroring her own, and drawing her to the School of Assassins. But Ulín is far more interested in learning Stone Orphan’s language than deciding whom she wishes to kill.

Unable to contain their curiosity, Stone Orphan offers to exchange stories with Ulín to help her decide the fate of three men. By turns, Stone Orphan and Ulín narrate tales of love, suffering, exile, and self-determination, and two wounded souls find hope in each other through the radical act of listening.
