In 1993, mountaineer Greg Mortenson attempted to climb K2, the world's second highest mountain, located in the Karakoram range of Gilgit-Baltistan, as a way of honoring the memory of his deceased sister, Christa. As a memorial, he had planned to lay her amber necklace on the mountain's summit.[14] After more than 70 days on the mountain, Mortenson and three other climbers had their ascent interrupted by the need to complete a 75-hour life-saving rescue of a fifth climber. Mortenson became lost while descending alone, and became weak and exhausted. Instead of arriving in Askole, where his porters awaited, he came across Korphe, a small village built on a shelf jutting out from a canyon. He was greeted and taken in by the chief elder of Korphe, Haji Ali.[15]
Mortenson soon found out that the village had no school. To repay the remote community for their hospitality, Mortenson recounted in the book that he promised to build a school for the village. After difficulties in raising capital, Mortenson was introduced to Jean Hoerni, a Silicon Valley pioneer who donated the money that Mortenson needed for his school. In the last months of his life, Hoerni co-founded the Central Asia Institute with Mortenson, endowing the CAI to build schools in rural Pakistan and Afghanistan.[16]
According to the book, Mortenson faced many daunting challenges in his quest to raise funds for the building of more than 55 schools in Taliban territory. Some of these challenges included death threats from Islamic mullahs, long periods of separation from his family, and being kidnapped by Taliban sympathizers.[17]
