Fascinating portrait of one of the world's greatest natural wonders, weaving together the wildlife and social history of the longest river in the world. From ancient Epypt, it takes a modern journey upstream as the river splits into its two main arms, the White Nile and the Blue Nile. Among the landmarks featured is the spectacular Blue Nile gorge - Africa's Grand Canyon. The book also follows in the footsteps of the great Victorian explorers who raced to solve the riddle of the river's source.
