Another good source for historical novels about American history are the books written by Michael Shaara and his son Jeff.
Michael Sharra wrote the famous "Killer Angels" about Gettysburg, that was made into a movie.
These cover the Revolution, the Mexican War, the Civil War, WWI, WWII, and Korea.
These are well researched, and tell history in a novel format centering on an individuals experience.
An eye opener was the novel about the Marine's in WWI. I knew it was bad, but had no idea it was that bad.
For one of the best history series ever done on WWII is the three massive book series by Rick Atkinson.
"Army At Dawn" covers North Africa, "Day of Battle" covers Sicily and Italy, and "Guns At Last Light" covers D-Day to the end of the war.
The Greatest Generation was just that.
We owe.
