In Tropic of Capricorn, bestselling author Simon Reeve embarks on a 23,000-mile trek around the southernmost border of the tropics - a place of both amazing beauty and overwhelming human suffering. Heading east through Africa, Australia and South America, Simon encounters breathtaking landscapes and truly extraordinary people: from Bushmen of the Kalahari and Namibian prostitutes battling with HIV to gem miners in Madagascar and teenagers in the Brazilian favela once described as the most dangerous place on earth. It is a collection of daring adventures, strange rituals and exotic wildlife, all linked together by one invisible line.

Like the best travel writing, Tropic of Capricorn confronts important issues of our time - our changing environment, poverty, globalisation - by taking us on an unforgettable journey of discovery.
