I like to read books about true events also, and my reading interests mostly center around Native American and Sports stuff. My wife is a high school librarian so I have access, plus by law she is required to order X amount of new books per year and if student requests don't meet her quota then I usually come up with a list. I have read all of these and would recommend them if they are topics anyone is interested in.
Empire of the Summer Moon- S. C. Gwynne
The Lakota Way- Joseph M. Marshall II, just two chapters in, but is a good read centered around humility, respect, honor, love, bravery, etc
The Journey of Crazy Horse- Joseph M. Marshall III
I Am a Man- Joe Starita
Geronimo Leadership Strategies of an American Warrior- Mike Leach (WSU football coach) and Buddy Levy
The White Indian Boy- Elijah Nicholas Wilson (the exact book my wife got was The White Indian Boy and Return of the White Indian Boy, I think this may be two books in one not sure...but great read and a lot of historical information about Jackson/Wilson area of WY)
The Gauntlet Runner- S. Thomas Bailey (Historical Fiction based on French and Indian War)
How Lucky You Can Be- Buster Olney
Wooden: A Lifetime of Observations and Reflections On and Off the Court- John Wooden
The Animal Keepers- Donn Behnke
I will also second Rowdie's Black Elk Speaks as I have read that as well.
I read Blood Meridian by Cormac McCarthy because in one of the other books I read they recommended it...I HATED it...can't believe I finished it, but I was hoping the one guy would die a terrible death in the end so maybe that is why I kept reading...
Meelosh...having the wife order The Tiger tomorrow!
