Mar 20, 2009 — Mexican and central American immigrants--most in this country illegally--have become a fixture on hundreds of dairy farms in northern New York and Vermont. In fact, they've become crucial to many farms' survival. Meanwhile, the farmers themselves, and their families, are in involved in a degree of illegality they're not used to. It's this underground world meeting sanguine farm life that's the backdrop for the latest novel by Julia Alvarez. It's a book for teen readers called Return To Sender. Alvarez is one of America's most famous Latina authors. She wrote How the Garcia Girls Lost Their Accents and In the Time of the Butterflies. Alvarez was born in the Dominican Republic, but she's lived the majority of her life in Vermont. She's taught at Middlebury College since the 1980s. She told David Sommerstein when she first moved to Vermont, there were very few latino faces.
