The story takes place in the distant future on a world called New Sparta, shortly after the Irredentist rebellion has been put down. Edward Maret, a wealthy and likeable young man, is about to get married, but doesn't realize until too late that he has enemies close at hand. As a result of their betrayal, Edward disappears into the bowels of the police establishment, only to emerge as a zombie-like cyborg (AX-17). After surviving several years as a cyborg-soldier who has no memory of his human life, AX-17 is captured by the alien Kliya, who initiate a process that leads the cyborg to regain his human identity.

Edward Maret re-emerges--a man betrayed, a man who suffers incalculable pain, a man who has lost everything, including the love of his life. The brutalized man journeys across the galaxy to the Confederation, where physical existence has become a burden to humans, who spend most of their "real" lives in a virtual world of wish fulfillment.

Eventually, he returns to New Sparta with a new identity and a plan to obtain his revenge. Piece by piece the elaborate plan falls into place. Yet at the climax, Edward is forced to look deeply into his character and motivation, while coming to terms with his past.
