Book excerpt: In 1823, Hugh Glass did the unthinkable: he wrestled a grizzly bear...and won. But that is only the beginning of the remarkable tale--Glass, badly mauled with a broken leg, was 200 miles from help. Determined, he set his own leg and made the long journey first by crawling, then by floating down a river. Following the freak encounter with the bear, Glass became a legend. He's considered one of the greatest American hunters, and knew the frontier like few people before or after him. This book tells the incredible stories that made up his life.
