Author Hugh Thomson admits he is not a mountaineer yet his book `Nanda Devi' is about one of the most beautiful mountains in the world. In 2000 after years of closure by the Indian Government permission was granted for a party to enter the Nanda Devi Sanctuary, a virtually inaccessible lost `Eden'. This enchanting high level area was first reached in 1934 when Eric Shipton and Bill Tilman entered via the Rishi Ganges Gorge, and the 2000 expedition, taking the same approach, was led by Eric's son John. Invited to take part with a mixed group was Hugh Thomson; an explorer, writer and film maker with experience in the Andes and other remote places. As well as eloquently and expressively describing the trek to the Nanda Devi Sanctuary Hugh Thomson comments with sensitivity and empathy (and humour) on fellow travellers, on a variety of individuals and organisations linked to Nanda Devi, and on the people he meets, together with insights to their cultures, religions and politics. He explores the dynamics of the expedition and he probes into the motivation of others, reflecting on differing attitudes and ambitions with Shipton and Tilman compared against the "supremacist climbing culture" of today. The book is a delightful read, but there is not enough of it - just over 100 pages of text - though an additional 24 pages of well chosen colour photographs balance this, and they fit nicely with the narrative. Past incidents like the tragic death of Nanda Devi Unsoeld or the CIA's secretive placing a nuclear powered spying device could have received more attention - and Thomson's own comprehensive Bibliography points the way.
