What is the theme in The Names by Don DeLillo?

Expatriation is a central theme in this story. The Names pointedly covers the territory of Americans abroad previously examined by Henry Miller, Paul Bowles, Allen Ginsberg and so on. It is an expatriate novel for the latter twentieth century.

The characters of The Names are not hedonists who have left the United States in search of a freer state of being; they are bourgeois professional who have parleyed discontent into a professional situation that allows them to live a rootless existence.
