This collection, second in a series, presents the seventh, eight, and ninth novels of Edgar Rice Burroughs' enthralling Tarzan of the Apes. In Tarzan the Untamed, World War I disrupts the peaceful life of Tarzan with his wife Jane on their East African estate. Taking up once more the way of the savage ape-man, Tarzan vows vengeance against the German soldiers that he believes to have murdered his wife. His adventures take him through and across a deadly desert, fighting enemies all the way. In Tarzan the Terrible, Tarzan finds himself in the mysterious country of Paul-ul-don, an evolutionary island in the African jungle interior. Here dinosaur descendants and intelligent tailed ape-men live amidst fabulous lost cities. In Tarzan and the Golden Lion, our hero rebuilds his life in Africa, only to be abducted and held prisoner in the lost city of Opar, whose priestess would have him as her mate. Trekking through the legendary Valley of Diamonds, Tarzan finds himself followed by a mysterious man--who is Tarzan's own double! From his stirring descriptions of the jungle itself to his adept conjuring of scenes of action and mystery, Burroughs does not fail to deliver the thrilling narratives that have made Tarzan so very famous.
