They arrive from around the world for countless reasons. Many come simply to make a living. Others are fleeing persecution in their native countries. Millions of immigrants risk deportation and imprisonment by living in the U.S. without legal status. They are living underground, with little protection from exploitation at the hands of human smugglers, employers, or law enforcement. Underground America, from the Voice of Witness series, presents the remarkable oral histories of women and men struggling to carve a life for themselves in the U.S.

Peter Orner edited Underground America and co-edited Hope Deferred, and is the author of four books of fiction, including the novels The Second Coming of Mavala Shikongo and Love and Shame and Love. His most recent book, Last Car Over the Sagamore Bridge, was a New York Times Editor's Choice and named a Favorite Book of 2013 by the Wall Street Journal.
