A Gift from Earth聽is about the social upheal on the colony world of Plateau, and is set in the early days of Known Space. The only livable area on the planet is a large mountainous area (Mount Lookitthat) which rises forty miles above the hot poisonous atmosphere below. Plateau is about half the size of California, and with such space restrictions, nothing can be wasted in the colony, least of all body parts. The biggest crime on Plateau is to commit suicide by jumping off the edge and therefore preventing your body parts from being re-used via the organ banks. Most crimes, even insignificant ones, therefore, he capital punishment as the deterrent.
The political structure of Plateau is divided in half, with the descendants of the original Crew hing the upper slice of the cake. With the organbanks at their whim, Crew live long healthy lives. On the other end of the scale are the colonists, who do the majority of the work and serve as fodder for the organbanks, and only get to benefit from them themselves if they are extremely loyal, or wealthy.
Such a structure can't last forever, and when young Matthew Keller (himself the nephew of a revolutionary) exhibits some rare talents, both sides see him as the lynchpin in a new Civil War.
