Adam Tooze, Wages of Destruction: The Making and Breaking of the Nazi Economy (Viking, 2006).
Perhaps I'm getting lazy, but I think this reviewer did a pretty good job of outlining some of the strengths and weaknesses of this book. That being said, my contribution to the discussion is that this is one of the best history books I have read in a long time. It took a subject I expected to be very dry and arcane, and made it interesting and provocative, in a well-researched and well-written package.
