From the snowcapped summit of McKinley to the ultimate challenge of Everest, this is a story about daring to dream in the face of a seemingly insurmountable limitation. It is about finding the courage to reach for that ultimate summit and transforming your life into something truly miraculous.In this inspiring memoir, Erik Weihenmayer shares his struggle to push past the limits imposed on him by his visual impairment - and by the assumptions of a seeing world. He speaks movingly of the role his family played in his battle to break through the barriers of blindness. And he tells the story of his dream to climb the world's highest peaks. Only 100 mountaineers have climbed all Seven Summits, the highest peaks on each of the continents, and Erik is joining that elite club.
