Bogdan, Absolutley American is a good recommendation for a book about West Point. I can recommend two other books:
Battle Dress by Amy Efaw Duty First by Ed Ruggero
You should be able to find all three of these books in your public library. Just remember that they are somewhat dated. West Point is continually improving the cadet experience.
Do not ignore the Amy Efaw book because it is gender specific and in the juvenile section of your library. It is an excellent, quick read. I think it is very important for any cadet to understand the female viewpoint of the West Point experience.
Have you visited? The overnight and the day visits are both very informative. On either type tour you get to spend one on one time with a cadet and see a typical cadet day.
