Lourenço and Pedro, two workers on a rubber-tree plantation in the Amazon, explore the rain forest's mysterious back-country during the flood season. Their tales of peril and last-minute rescue, brutal savages and men of honor, snake-worshipping armies and half-ape Lost Races — and much more — offer some of the most exciting pulp fiction ever written. For in the shadows of the rain-forest, many evils lurk . . . human and otherwise! Features a new introduction by Darrell Schweitzer, 8 short stories, and "The Jararaca," a complete novel.
