"...I like the way you circle back again and again to several events to re-dig them up, new embellishments and revelations each time. This also made the book seem rather dream-like (a fevered dream, to be sure). Overall it left me wanting to hear and know more. Sometimes it read like a philosophical treatise, sometimes like an alternate socio-political history, and sometimes like a war/ human drama. The "hows" and whys" you presented are definitely not ideas I've ever heard, and I think are probably not at all mainstream, yet startingly plausible! That's what makes the book so eerily present..the actual possibility, through your experience..that this could have been the way things happened.
Which send some shockwaves through everything American if we even consider the possibilities you reveal! Certainly the unique angles (The Sister's point of view and story, Nhu's presence, etc.) show the whole "war novel" experience from uniquely different angles. One thing the book left me wanting to know more about was about your Bronze Star. That's an almost hidden mystery and teaser, that you "didn't" say a whole lot about that..."
