Madre de Dios - 'Mother of God' - is a place where the Andean Cloud Forest intermingles with the steaming tropical jungle at the head of the Amazon river. Here can be found the greatest proliferation of living species that has ever existed on Earth, ever. And it is a place which is now under grave threat. Paul Rosolie has travelled to the very heart of this wilderness in search of rare flora and fauna. His adventures - with giant anacondas, huge cayman, the mighty jaguar and one very small anteater - are by turn thrilling, terrifying and revelatory. Paul crosses some of the world's harshest terrain and encounters some of its most extreme weather conditions. He battles with life-threatening tropical diseases and the extreme mental challenges presented by being alone in the heart of the jungle. Mother of God is an astonishing tale of adventure and survival, set in one of the world's few remaining truly wild places. It's a story of nature, red in tooth and claw, and how we must both respect its awesome power and protect its extraordinary glory.
