Erik Weihenmayer accomplished the unthinkable when he climbed to the peak of Mount Everest despite being blind. His daring especially impressed Sabriye Tenberken, a blind educator and adventurer who established the first school for the blind in Lhasa. She invited Weihenmayer to meet her teenaged students. Together they concocted a plan of astonishing courage to lead six of the blind teenagers on an ascent up the 23,000-foot Lhakpa Ri peak on the north side of Everest.
