This is the fourth story in the TARZAN adventure novels. This time it is the son of Tarzan, the young Lord Greystoke, who leads us away from the sheltered shores of 19th century England, back to the primitive jungle. Young Lord Greystoke quickly asserts his natural authority in the jungle the way an heir-apparent might ascend a throne but not without a few painful learnings. Accepted by his fellow primates, they rename him, Korak "the killer." He is as powerful as he is clever. Though his transformation is successful, it is not without bloodshed.
