Read through Stalingrad and Berlin by Beevor when I were a kid, great books. Haven't revisited them for 4-5 years though. Got a load of books, most in swedish though so they are pretty hard to find translations for (since they often are not direct) my favorite have always been "World war :A photographic history". A book I've probably looked through 10 or so times. Contains tonnes of picture and a simple go through of the war including of course the eastern front. If you want a quick go through of WW2 that is broad as opposed to specific, 300+ page books, I recommend it warmly.
