Nu, a warrior from the Stone Age, is buried alive in an earthquake while stalking a saber-toothed tiger. Awakening thousands of years later on Tarzan's estate in Africa, he gives his heart to Victoria Custer of Nebraska, a visitor to the estate, who is the reincarnation of Nu's Stone Age love, Nat-ul. But other men treacherously compete for the love of Victoria in modern Africa and for the heart of Nat-ul in the distant past. Set in both a terrifyingly dangerous primeval setting and the beloved world of Tarzan, The Eternal Savage reveals whether eternal love is strong enough to triumph over undying adversity.
