Welcome back to Asberek where a fledgling colony struggles in the isolated reaches of space. Danger stalks the colony and two people, thrown together by circumstances, may hold the key to survival on this distant planet. Dr. Jenia Carstairs' job is to study the chemical that permeates the atmosphere on Asberek. But Synthetic Endorphins Xstasy (or S.E.X.) is a problem. It creates increased S.E.X.ual desire in humans, driving them wild with tantalizing erotic fantasies that beg to be explored. Dr. Carstairs is not immune to its effects and suddenly finds herself consumed with lust for an enigmatic stranger. Tribunal soldier Paul Lestrano hunts a Rogue Tribunal who escaped to Asberek after an attempt to destroy the colony. His pursuit leads him directly into the path of a woman who holds both the future of the colony and Paul's needs in her hands. As the chemical drives them to greater heights of S.E.X.ual fantasies, Jenia and Paul explore each other's most intimate S.E.X.ual desires and find the taboo secrets locked in themselves. Their journey brings them to the brink of destruction, but self-discovery and ultimate desire are often found wrapped in the haze of S.E.X.
