The Jewels of Aptor
Delany’s first novel, from 1962, serves as a sort of prologue to the subsequent Captives of the Flame, 1963. Set several centuries after the Great Fire — a nuclear holocaust — a young woman seeks her destiny with the help of a four-armed youth. (Summary by BellonaTimes)One of my favorite books growing up – found it as an audio book for free.
