Killer Angels by Michael Shaara
"The Killer Angels" is a fictionalized account of the Battle of Gettysburg. The story switches back and forth between different people from both sides and helps explain the reasons both had for fighting.
I liked this book much more than I thought I would. The story was well written and turned something I thought I knew into something new. For a well-known historical event, the book brought a little page turning wonder to it.
