Far in the distant future, the human race has spread out among the cosmos, meeting (and bedding) as many alien species as there are stars in the milky way, making way for an unprecedented era of peace and prosperity for all life in the universe. At the heart of this new civilization sits Ganymede station, a post monetary paradise of scientific and artistic advancement, where Starla Cascade, beautiful and mysterious courtesan, uses her unique intimate skills to improve the lives and love lives of her many clients of all species. Starla has been approached by the representative of a mysterious client who can provide her with vital information in her ongoing hunt for the villainous void dweller Forsyth. The only catch? He won't tell her his name or his species, and she can never see his face. Can Starla stand being left in the dark? Or will fear of the unknown leave her floundering in waters too deep to swim?
