Query: A Marvelous Book

This is one of the best novels I have read. Well-written, original and insightful. It is a book about relationships, broken families, and the cultural chasm that separates idealistic Westerners from the reality of the lives they seek to change. I read this book years ago, but there are lines and images that I have never forgotten. A masterpiece. Pity, she is not producing more.
