I'd recommend you read all of Stephen Ambrose's books about WW2. He's the guy that wrote Band of Brothers. One of the best, most readable historians ever.
So far I've read (of his 30+ books);
Citizen Soldiers: The U.S. Army from the Normandy Beaches to the Bulge to the Surrender of Germany, June 7. 1944 - May 7, 1945
Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Owning of the American West
D-Day June 6,1944: The Climactic Battle of World War II
Band of Brothers: E Company, 506th Regiment, 101st Airborne From Normandy to Hitler's Eagle's Nest
Pegasus Bridge: June 6, 1944
Crazy Horse and Custer: The Parallel Lives of Two American Warriors
The Wild Blue: The Men and Boys who Flew the B-24s over Germany
The Victors: Eisenhower and his Boys - The Men of World War II
