What is the main setting in the novel, Glitch?

The Community is an underground city in which Zoe and most of the other characters live. It is controlled by the Uppers, who have inserted V-chips into all residents in order to maintain complete control over them, but maintaining that this is a good thing that protects them from the destructive urges and emotions that destroyed the Old World.

Although it is gray and drab, the Community functions much like a regular city. It has schools, a Market Corridor for buying groceries and other items, housing units and a subway system for transportation.
