Query: a remarkable, heartbreaking story

Most Americans have little idea of what happened in Vietnam after the last helicopter left the U.S. Embassy roof. This memoir--which is brutally painful to read at times--is by far the most detailed account of the chaos that tormented Vietnam in the first ten years of Communist rule that you'll find. Something tells me that a sequel chronicling how Nguyen evolved from 18-year-old immigrant to 33-year-old New York dentist would be just as fascinating. I hope he's writing it.
