Despite his well-document track record of pushing beyond his physical limits and emerging from life-threatening situations mostly unscathed, Theodore Roosevelt’s journey through uncharted regions of the Amazon almost broke him. What started as a comically arrogant march through the jungle ended with TR contracting malaria, gravely injuring himself, and begging his son to leave him for dead. The book offers a revealing peek into the life and psyche of one the most spirited U.S. Presidents.
