Book excerpt: Don Sheldon has been called 'Alaska's bush pilot among bush pilots', but he was also just one man in a fragile airplane who, in the end, was solely responsible for each mission he flew, be it a high-risk landing to the rescue of others from certain death in the mountains of Alaska or the routine delivery of supplies to a lonely homesteader. Read James Greiner's Wager with the Wind to learn how a hero was born, and also how he made his courageous journey to the unknown skies of dealing with cancer.
