In her latest book, Julia Alvarez writes about Mexicans who've left their country and their culture behind. Return to Sender takes a close-up look at the lives of people who are often regarded as troubling statistics in the immigration debate — the children of undocumented workers who come to the U.S. each year to find work, and who live in fear of being sent back to Mexico. The book is written for children.

Julia Alvarez talks with host Peggy Wehmeyer.
