Bailey Cove Evening: River of Doubt

River of Doubt by Candice Millard
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.

In the process, he changed the map of the Western Hemisphere forever.
