En las Sombras de Estados Unidos is the Spanish translation of Underground America, the third book in the Voice of Witness series. It focuses on the difficult lives of undocumented workers in the United States, showcasing oral histories of men and women who have come to America seeking a better life for their families, only to be subjected to dehumanizing working conditions. This book gives voice to these often unknown individuals who are the backbone of our economy, supporting myriad industries by working the least desirable jobs — people who, for living in this country without legal documentation, are sentenced to lives without the most basic legal protections. Translated from English by novelist Peter Orner and journalist Sandra Hernández, En las Sombras de Estados Unidos asks a largely ignored part of our country to finally tell their stories.
