''America City'' tells the story of Holly, an ambitious publicist who sets aside her own political beliefs in order to help the ambitious Senator Slaymaker with his Presidential campaign. Set in the 22nd century, the novel tells of an incredibly disunited United States, where the effects of climate change have created deep divisions between the affluent Northern States, and the South, which is frequently ravaged by extreme weather. Holly and Slaymaker hope to change this, working together on the plan they believe to be the solution to the problem of where to place the thousands of Americans who have been made homeless by devastating storms.
