How does author, Joan Didion, describe the city of Miami in the book, Miami?

Miami is described by Didion as an exotic, tropical city seething with energy, activity, intrigue, and tension. She claims that the tropical climate mirrors the intensity and heaviness of the Cuban exile community's feelings and time and again compares the physical environment to the emotional milieu she experiences in Miami. In this book, her focus shifts from Cuban exiles' ideological battles to tensions between ethnic groups in Miami, to ideological divisions between the aforementioned exiles, and finally to Washington's role in what transpired in Miami from the 1960s to the 1980s.
