The Civil War, three part series by the late Shelby Foote. It may take you awhile though. Although if you have an affinity toward the Civil War, it is a labor of love. Just for clarification, it is nonfiction, a historical narrative of the entire war.
Actually I took a test not too long ago and wrote that if I could go back to one era it would be the civil war time so that would be very interesting for me. Thank you.
