Eugenicists believe Teakh Noahee to be innately monogamous and altruistic—a load of shine according to him. He passes himself off as a fisherman while blackmailing poachers. Regardless, his DNA may hold the key to male survival on the harsh ocean planet of Fenria.
This novella has been described as "trashing space alien porn," although it isn't in space and doesn't have aliens. Be forwarned. However, it does have bisexuality, polyamory, and female-centric eroticism. It's very much speculative fiction and in the tradition of Kushiel's Dart by Jaqueline Carey and Venus in Furs by Leopold von Sacher-Masoch.
It occurs about 60 years after The Fisherman and the Gene Thief and Annin's Bargain..
