The Fisherman and the Gene Thief
A futuristic fisherman losses his heart and his semen to black marketeers.
On a planet with three women for every man, eugenicists believe Teakh Noahee to be innately monogamous and altruistic. He loses a spoonful of his seed to a mysterious trio of women. They are succubi, professionals who sell semen on the black market. Teakh falls in love with one of them. Determined to assist in raising his children, he rebels against the matriarchy and sets his own course, founding a new clan that treats men and women as equals, all for the love of the woman who cheated him.
