The River of Doubt: Theodore Roosevelt's Darkest Journey

At once an incredible adventure narrative and a penetrating biographical portrait, The River of Doubt is the true story of Theodore Roosevelt's harrowing exploration of one of the most dangerous rivers on earth.

The River of Doubt; it is a black, uncharted tributary of the Amazon that snakes through one of the most treacherous jungles in the world.

Indians armed with poison-tipped arrows haunt its shadows; piranhas glide through its waters; boulder-strewn rapids turn the river into a roiling cauldron.After his humiliating election defeat in 1912, Roosevelt set his sights on the most punishing physical challenge he could find, the first descent of an unmapped, rapids-choked tributary of the Amazon.

Together with his son Kermit and Brazil's most famous explorer, Candido Mariano da Silva Rondon, Roosevelt accomplished a feat so great that many at the time refused to believe it.

In the process, he changed the map of the western hemisphere forever.
