Question:

Does anyone know the name or the author of a book where a migrant worker gets hit by an OC man and gets $20.?

Its a book by a Californian writer about two families whose lies intersect after the OC man hits the migrant worker with his car and gives him $20 and let him go on his way.

Best Answer - Chosen by Asker: "The Tortilla Curtain" by T. Coraghesson Boyle.

Great book, btw. Absolutely savage sendup of certain aspects of the California lifestyle.
