This is a well written, thoroughly researched story about a nearly fatal journey which Theodore Roosevelt took to South America following his 1912 election defeat. Along with a carefully organized group of Brazilian military, naturalists, and his son Kermit, he undertook to descend a previously uncharted river in dugout canoes. (A journey of four months overall). The party encountered hostile Indian tribes (who had never seen white men), rapids and waterfalls, deadly animals and insects, diminishing supplies, and sickness along the way. In the end, they persevered and the river was named Rio Roosevelt.
The narrative is full of historical, geographical, and biological information which makes it an informative and entertaining book to read.
