Diversity: Mestizos, Latinos and the Promise of Possibilities. By Amardo Rodríguez. ISBN: 978-0-915745-92-0. $18.95. This book is about the hope that resides in brown, the color of creation. It defines brown ideologically rather than racially. That is, brown is about peoples who are increasingly defying the borders of ethnicity, nationality, sexuality, and race making us afraid of our differences.
