What happens when two great public figures, historical figures from the United States and Brazil, come together to undertake a bold and dangerous adventure: an expedition through the Amazon jungle in regions never before traversed by man? This is the story of the Roosevelt-Rondon Expedition, carried out between 1913-1914. Rondon had discovered the River of Doubt on a previous expedition and, together with Roosevelt, led a new endeavor to explore the long course of the "River of Doubt," later renamed the Rio Roosevelt. Upon returning, weak and ill but alive, Theodore Roosevelt wrote the book Through the Brazilian Wilderness, detailing all the specifics of the perilous adventure in the Amazon jungle. Through the Brazilian Wilderness is an epic adventure, narrated by one of its protagonists. It is an exciting read from beginning to end.
