Born Robert Kilgour, the child of missionaries killed in Africa, Ki-Gor grew up in savagery, but developed a noble, generous spirit. When red-headed Helene Vaughn's plane crashes in the jungle, Ki-Gor rescues her. How can she resist falling in love with this superbly-muscled, child-like giant, who is unspoiled by the corrupting influences of civilization? But this classic idyll of "Me Ki-Gor. You Helene!" is threatened when the jungle lord's mate is captured by raiders and she is threatened with becoming the "Bride of the Serpent God", a ravenous, twenty-foot python. Then Ki-Gor himself is targeted for death by the evil "Warrior-Queen of Attila's Lost Legion." Accompanied only by his companions, Tembu George, the giant Masi warrior, and the pigmy chief, N'Geeso, Ki-Gor must battle the savage jungle beasts, cruel nature, and the treachery of men, if he and Helene are to survive the perils that threaten them and return in triumph to their tree-top home.
