Best WW2 Novel (fiction) that I have read is "The Berkut" by Joseph Heywood. Out of Print and hard to find it deals with an SS officer's attempt to sumggle a very alive Adolph H. out of Germany and with the Soviet Special Operatives trying to stop him.
Best piece of WW2 Non-fiction I read is any of the books by Stephen Ambrose, Citizen Soldiers being the best I think.
