Query: Triumphant and Tragic

Were it not for fascinating books of American history, like this one, episodes of our illustrious, and tragic, past might be easily forgotten. That the Lewis and Clark expedition is an interesting story is an understatement, but what sets this book apart from other interesting books of history is that Ambrose does not allow the reader to shelter himself/herself from the hard personal questions about leadership and personal tragedy. I found myself reflecting on my own style of leadership, and my own personal failures and triumphs. A novel of exploration could not have been better written nor conceived.
