It`s 2131 A.D.. Deunan Knute had been a soldier in the battlefields for most of her life. When the World War ends, she`s transported to the city of Olympus to live peacefully and finds out that, in an effort to protect the human race from future wars, humans have created the Bioriods, a geneticaly enhanced race of people that have restrained feelings and therefore cannot hurt each other.

She discovers, however, that not everyone is happy with this Human-Bioriod symbiosis: many humans treat Bioriods as a lower species and a threat to their future, the human-controlled Military is seeking annihilation of all Bioriods and the Bioriod-controlled government is afraid of a coup d` etat.

The task falls on Deunan to bring peace to the world again. In this she`s aided by her former lover, Briareos, who has lost his body in war and has become a cyborg: a brain in an artificial body.
