I don't read a great deal of adventure/travel writing, but Simon Chapman's The Monster of the Madidi is a fantastic romp through the jungles of Bolivia. The premise of the trip is a search for the legendary DeLoys' ape, of which we have only a photo from the 1920s and plenty of local accounts of its reality. I won't reveal if Simon found the ape, but the story of the search makes great reading full of log jams, murky jungles, "hostile" locals, inept flight officials, screaming monkeys, hitch hiking Australians, and--well you get the picture. A fun read.
