Little covered WWII topic
There are many books about the 2nd World War, but most cover the main topics of the war. This book covers war in the Atlantic ocean. A well written and entertaining book. Unlike many history books, it's easy to read and is basically comprised of about 37 chapters, each covering a different aspect of conflict in the Atlantic. Many of the chapters discuss the fight to deliver supplies to the British and later the American troops. Submarines, and building of a merchant fleet.

Most sea books cover the major battles in the Pacific such as Midway. However, most of the battles we know of only lasted a short time, perhaps just hours. The war in the Atlantic lasted the entire length of the war and was vastly important to our victory. I think you'll enjoy this one, even if you are not a history buff.
