The Great Bridge is a phenomenal engineering story (and so much more). The Rise and Fall of the Third Reich was chilling but I'd read it again. Simply fascinating, written by a western reporter who was actually there.
I second Rise and Fall of third reich. I was fairly knoweable of the overall history but this book contains very pertinent insights to so many mechanisms at work when germany transitioned into third reich and how the war progressed. The only downside was that the author issues quite deragatory comments of the nazi subjects of the book which, while perhaps warranted, are stylistically awkward in a history book.
