Few true humans remain on the future Earth, where caimen, shrugleggers, and felinas dominate. The peoples are descendents of crocodiles, alien races, and jaguars, and they are much different than the humans - they are products of genetic experiments, created to perform specific functions. Some work in the swampy lands, others are the strong burden-bearers, but none are as beautiful as the felines - not even the humans. And no one is worthy enough to win over the most attractive felina, Karina. She is a rare beauty of great prowess, with a tempting sculpted physique that could lure anyone to her.
