Lords of Discipline, Pat Conroy

The story of Charlestown, and the brutal hazing at the Citadel, and life in South Carolina in the 60's.

Calebs Crossing, Geraldine Brooks

A native American is a main character, but it is told through a girl who befriends him; he is one of the first Native Americans to go to Harvard.

The Killer Angels

I read this in Gettysburg; it is a really interesting account of the battle, the generals, the setting etc.
