Seeds of Change — Thomas F. Monteleone

The Denver Citiplex that evolves over the next two centuries, while technologically a masterpiece, is a living hell for those whom computer analysis labels potential deviants from the genetically controlled social norms. In his frantic effort to escape the fate of all such deviants, Eric Stone and his beautiful girlfriend, Jessica, manage to reach an underground colony living in the wastelands outside the city. It appears that not everyone loves the Citiplex, but only the arrival of a small colony of earthling survivors from Mars enables the dissidents to hope they may make some changes. But it is only a hope.
