The novel describes the travels and perils of Freya Nakamichi-47, a gynoid in the distant future. Humanity is extinct and android society has assumed a near-feudal form, with "aristos" and "arbeiters" (a term from the German word Arbeiter, worker) having spread throughout the Solar System. Freya, a robotic courtesan at loose ends after the mysterious extinction of the human race (her "One True Love"), becomes a courier for the Jeeves Corporation and learns of a shadowy conspiracy to overturn, or perhaps even control, android society. Soon she is on the run with her identity and her very existence threatened.
The novel includes numerous references to the works of Isaac Asimov and Robert Heinlein, especially to Asimov's Three Laws of Robotics, which were not used for controlling the robot society because of loopholes, and Heinlein's novel Friday, as the protagonist is an artificial woman, designed and trained to make love to humans and meet their every erotic desire, in a time when none exist, and any near match overwhelms her with lust and romantic longing. Freya and her kind are condemned to an existence without love, and must face suicidal despair and the murderous whims of their rulers alike.
She travels extensively at the bidding of a mysterious "Boss," and impersonates an aristocrat traveling on a spaceship as part of a mission in which she carries a mysterious egg tied to a plot to overthrow an empire. She also has a relationship to a male android named "Pete." Even her name (Freya) hints at Heinlein's novel, and she is actually called "Friday" at one point, likely as a joke.
