Two of the UK's finest historian, both give great coverage. Gilbert's book gives a lot more detail and it's about twice as thick.

John Keegan, unlike many other authors, includes the effect of the Allies breaking the Axis codes in his analysis. And Keegan's writing is terrifically readable.

Pat Buchanan's work is indispensable

And if you really want some of the real, primary sources, David Irving is the man who dug them up.
