If you want to understand immigration across the U.S.-Mexican border, read this book. Urrea traces the trip of the Wellton 26 (or, ultimately, the Yuma 14) from their homes in Veracruz through to their torturous trek through the Arizona desert. This is an incredibly compassionate and empathetic piece writing, with enough blame *and* understanding to go around for the immigrants, the coyotes who guided--and then abandoned--them, and the Border Patrol ("La Piche Migra").
