They are sort of standards and excellent books.
This is a recent book and if you like WW II stories, here are a couple more suggestions. All are easy to read and not cluttered with infinite detail. I have ADD (means I suck at math) and tend to go for the easy reads.
Try Flag of our Fathers and Fly Boys, both by the same author, James Bradley. Master of the Air by Donald L. Miller, is a good read also. This book has some amazing statistics (although a bit more statistical than other books mentioned, it is interesting statics for those lousy at math and interested in WW II trivia, facts and figures and planning, or lack thereof. It tells of horrendous hardships and massive losses suffered by bomber crews sent over Germany.
A couple of pieces of trivia:
Do you know that around 1938, there were more men in the New York City Police Department than there were men serving as U.S. Marines?
Or the U.S. Army Air Corps lost more men in battle than did the U.S. Marines in all battles fought during WW II?
This is not to try to trivialize the Marine Corps but to point out how unprepared the U.S. was prior to war with Japan and while heroes came from all branches of the military, air men suffered staggering losses over Europe. Consider that every time a B-17 bomber was shot down, ten lives were lost.
