Query: A Rare Insight into Life

It is not often I find myself regretting most of the five star reviews I have written.This is one of those occasions. It is not often when I read a novel that works on two levels. Purple Sun is one of those rare books.All stories have a purpose. Most of the time, it is to entertain the reader. This book certainly does that. A Master Sergeant, a lieutenant with little in common except a mutual concern about a twice-wounded marine who they suspect who went-over-the-hill during a nighttime fire fight one night in Vietnam.With help from a former Viet Cong soldier and small-town newspaper editor 28 years later they return to the former war zone to attempt to uncover the truth about what happened to the young soldier.The story is compelling. However, this book reveals more. From within in its pages emerges an understanding of what it means to be human.Purple Sun should not be missed. It is a story that will stay with you for years to come.
