How can you not love a book whose last chapter chapter begins, “In the morning we ate more piranhas”, right below a marvelously detailed pen-and-ink drawing of a Bird-eating spider eating a . . . bird. In this great travel book, subtitled, A Journey Between the Orinoco and the Amazon, O’Hanlon recreates the 19th century Englishman’s dogged exploration of a place where no person with any sense (but a lot of adventure) should visit.
