It is a WW2 book written by Stephen E. Ambrose about Operation Overlord (Allied invasion of Normandy beaches occupied by Nazi Germans). It details both preparation and actual day of Operation Overlord. It is wrapped with book plastic wrap. Still in good condition though it may look old. Stephen E. Ambrose is my favourite author and his books are really good and easy to understand. He wrote military history in such a way that it becomes alive as you read it!
