The Luthier of Keman (A Children of Man short story‪)‬

Caleb Murphy is coming to the end of his first circuit as an avowed Daniyelan, and it can't end soon enough. Arbitrating judgments for horse breeders in Isfaridesh can't compare to his journeymen circuit riding the disputed Nabosian border, and his partner, Gisa Protz, can't stand him. His thoughts are with his troubled sister Ella as he arrives in the small town of Keman, but what awaits him in a luthier's shop will change his life forever.

"The Luthier of Keman" is a short story that takes place twenty years before Shatter (The Children of Man, #1).
