Blurb

The Artificial Kid is a science fiction novel by Bruce Sterling. It was originally published in 1980.
The Artificial Kid takes place on the planet Reverie, a world of coral continents, levitating islands, and the corrosive, transformative wilderness of "The Mass." Reverie has been transformed into a utopia/dystopia, with a stark class division. Arti, a heavily biologically modified boy from the Decriminalized Zone, becomes a pop star by selling videos of himself engaging in bloody combat with other fighters for the entertainment of the upper classes. When Reverie's founder, Moses Moses emerges from seven centuries of cryosleep, and Arti discovers an unpleasant secret about his past, both have to flee to escape from the powers of the "Cabal" that controls Reverie from behind the scenes.
