The Girl With a Symphony in Her Fingers — Michael Coney

Call them the spare parts of people. They chose the risk - jail for convicted crimes or semi-freedom as someone's bonded servant for the same term. The price was that they were body insurance. If their master lost a leg or an internal organ, they would have to supply the missing part. That was the risk. Sagar used bondsmen in his other-world farm where he raised exotic alien pelts to sell to the rich. He had no thoughts on the bondsmen problem, pro or con. But when Carioca Jones, 3-V star, visited him he met her bonded companion, the lovely girl with the musical talent.

It's dangerous to fall in love with a bondsmaiden. Doubly so when her mistress is in love with you. Triply so when it might set off the social explosion that had been smouldering beneath the delicately balanced surface of their post-cataclysmic Peninsula.
