Winner of the Pulitzer Prize and basis for the movie “Gettysburg.”  His son wrote a prequel (Gods and Generals) and sequel (The Last Full Measure), and, while not as good, they are both very appealing.  The Killer Angels is a must-read, as I have recommended it to nearly 100 people of all ages, races and genders, and all have told me that it is one of the best books they have ever read.  I never knew how interesting the Civil War could be, and I would recommend that all high school social studies teachers recommend this book to their students.  I would have been much more interested in this time in history (now I read every book on the Civil War that I can get my hands on).
