Elyria is a nightmare world, besieged by the Black Ship and its inhuman Passengers. It is also a world of uninhibited sexuality. Urna and Rune are an elite military unit working for the Lux, the totalitarian dictators who control the planet's last human stronghold. They share a deep passion, too, bound together by a past neither can clearly remember. When Urna can no longer abide the Lux's repressive control of his mind, he flees to join a band of rebels. Rune, heartbroken and furious, must hunt him down. Virge is a chemist who supplies the drugs that keep the Lux military obedient. When she and her sometime lover Bongo harbor the wayward Urna, she is caught up in a breathless carnal adventure that will lead her into the deadly shadow of the Black Ship itself.
