Book excerpt: Mount Everest - a place of mystery, majesty and unparalleled beauty - rises higher into the sky than any other mountain on Earth. Many stories have been told about the dangers and triumphs of climbing the summit - but few have been written about the Sherpa, the people who have lived on the mountain for centuries and consider it sacred. With stunning photographs and engaging text, Sacred Mountain presents a unique picture of Mount Everest - its history, ecology and people - that will captivate readers of all ages.
