Heinrich Harrer is an expert mountaineer from Austria who is in Asia at the outbreak of World War 2. He is sent to a camp in India, and after repeated attempts he escapes. He makes his way into Tibet, travelling through extremely dangerous areas with little equipment and resources, to avoid discovery and capture. Tibet is well known for not accepting visitors freely, yet with luck and bravado Harrer and his friend end up staying in the capital city, Lasa, as guests of the state.
They act as advisers to the government and Harrer becomes tutor of the child God-King, who happens to be the current Dalai Lama. Harrer makes his home in Tibet, not eager to return to a damaged Europe, until the Chinese invade Tibet and he is forced to flee.
Harrer was the first Westerner able to study Tibetan culture and society, and he made the most of this opportunity. The book give real insight into Tibet and the current situation, and also about the life of the Dalai Lama.
