Black Hearts is the most extraordinary work of nonfiction. Jim Frederick tells the story of the entire deployment of a group of soldiers in the triangle of death who suffered the most terrible losses and were under attack almost every day. They lived outside the wire in "the most dangerous place at the most dangerous time" in Iraq. Black Hearts is not just for those who like war books, it's a book for anyone who wants to read about characters, about human character, how it is tested, about how war really is (some passages are difficult to read, so raw and real), how humans interact, how they behave under the kind of pressure most of us will never have to suffer. This book is for anyone who wants to read a beautifully crafted tale, sensitively and fairly handled. You feel as if you were there, watching the soldiers the whole time, willing them to step back two inches, a step that would spare the insurgent a clean shot; urging leaders to choose this course of action, not the one that results in yet more losses, with little overall gain; urging those who ended up committing the worst crimes of the war to hold back, to dig deeper, find the good in their character, to spare the innocent Iraqis their lives, their brothers-in-arms the inevitable tainted-by-association. Black Hearts is about leadership, about friendship, about the extraordinary tests on the character of a person, why those who endure the same things cope, or don't. It's about why some people choose to behave the way they do. (The chapter on the rape of the girl and murder of her family by 4 soldiers --all now in jail in the US -- is extremely difficult to stomach.) There's nothing Hollywood -- though it would make the most incredible movie actually -- or sanitized about Black Hearts, so real are the characters and images conveyed. We need to know this is what war is without, thankfully, not debating the been-there-done-that pros and cons of going into this particular war. This is the best and most emotive book, not just war book but book, I have read in years. Some scenes made me weep openly. It has changed the way I think about men at war, about character, good and bad, right and wrong, how not every leader is a good one, not every soldier is a hero -- a point Frederick makes very well, -- mostly because soldiers and leaders are human, too. But it also makes you realize how an army needs to sort those who can lead from those who obviously cannot, that is those whose errors in judgment have catastrophic consequences, those whose orders decide whether people live or die and, for those that live, how they live, how they cope, how they work within the larger group, how they rebuild their lives outside the wire, inside, if they're lucky enough, and how they deal when they return home. This is stuff we need to know and think about. It would be an amazing book were it fiction. The fact it is not makes it all the more riveting and shocking. Frederick is an extremely talented writer. I absolutely recommend Black Hearts to all Amazon customers. (There are also more great reviews on Amazon.com and the New York Times called it "extraordinary" and "riveting", too.)
