One of the few contemporary historians to rival Keegan's treatments of WWII is Carlo D'Este. His earlier books on Sicily and Anzio are not always available, but grab them if you find them in a used bookstore. Meanwhile, Decision in Normandy is the best book I've read on Normandy. (Keegan's 6 Armies is close, but is not as comprehensive.) His biography of Patton is amazing in the number of new facts and stories he reveals about this legendary commander.
