Not at all a pleasant book, entirely because of its subject matter.
But it tells some truths about the Vietnam war that have been ignored, often on purpose, by our "news" media, our politicians, and our schools.
It's not for the faint of heart, but for anyone who wants a personal look at that terrible time, this is a good place to pay attention.
ADDED, right after I read some of the other reviews: Several of them claim many of the stories in this book are fiction -- some, I guess, even downright lies.
Why such a book got published is beyond me, if it is not true.
I guess, though, a reader should be warned.
