The Tortilla Curtain by T. Coraghessan Boyle

This is the story of two couples in Los Angeles: one, a wealthy writer and his real estate agent wife who live in an exclusive hilltop community; the other, illegal Mexicans, just trying to find work to survive. They are thrown together by a freak accident and series of events. The story is alternately told from each person's point of view. It explores the issues of immigration and racism in a very compelling story; it is very well written. I rate it 3 out of 5.
