In 2007 they wrote the Cicerone guide to Mount Kailash and Western Tibet, as well updating the Grand Canyon guide. During 2011 they revisited Tibet, this time driving the same old Land Rover back from Kathmandu to the UK overland via Lhasa, through China, Kazakhstan, Russia and Western Europe. Their latest books are the Cicerone Annapurna guide, published in January 2013, along with two Manaslu books -- a picture book and a detailed trekking guide -- published by Himalayan Map House in Nepal.
Siân and Bob met in 1983, on a trek from Kashmir to Ladakh. By then Bob had already driven an ancient Land Rover from England to Kathmandu (in 1974), and overland trucks across Asia, Africa and South America. He had also lived in Kathmandu for two years, employed as a trekking company manager. Before they met, Siân worked in computer programming and systems analysis, but was drawn back to the Himalayas after her first trek, the Annapurna Circuit, en route from working in New Zealand.
Since they met they have been leading and organising treks in the Alps, Nepal and the Sahara, as well as driving a bus overland to Nepal. Journeys by a less ancient (only 28 year-old) Land Rover from England to South Africa provided the basis for several editions of the Bradt guide Africa Overland.
In Kathmandu they now work with Himalayan Map House, and for many winters worked with Pilgrims Book House, producing cultural guides – Kathmandu: Valley of the Green-Eyed Yellow Idol and Ladakh: Land of Magical Monasteries – and a historical look at the Guge Kingdom, Kailash: Land of the Tantric Mountain.
