This book is one of my contenders to be remembered over time. The author is intelligent and insightful. The language is beautiful with creative metaphors that are helpful not distracting. The book is a mix of psychological reflection and action. It reminds me of Crime and Punishment but a lot more happens. It starts with the Fall of Saigon and moves to the US. There is combat and espionage and friendship and sex and cruelty and sympathy. I would recommend it to any reader who is willing to subject themselves to the subject matter. As a spy novel this is much more brutal than Clancy or LeCarre. This book is interesting and technically accurate as far as I can tell but it is emotionally intense and does not shrink from gritty realism regardless of the subject matter. I won't spoil it by giving further details, but yes, if you are up for the experience, read this book.
