For thousands of years the nomads of East Africa have protected the savannahs that are their livelihood. Today they and their land are threatened by bandits, farming and tourism. Ironically the biggest threat is conservation. Exposing some of Africa's best-kept secrets, the author travelled amongst the Masiti, the Samburu and the Turkani across some of the most hostile places in Africa. This is a controversial and adventurous travel book which also recognizes a spiritual journey as George Monbiot discovers what it means to be a nomad, and why many of us are not content to stay in one place.
