The Eternal Savage by Edgar Rice Burroughs.
Read in English by Mark Nelson.
Here is Nu, son of Nu, seeking to test his mettle against the terrible fangs of the ferocious saber-tooth tiger. Here is Victoria Custer, guest of Tarzan, seeking vacation and adventure and finding more than she could ever have dreamed of. Here is THE ETERNAL SAVAGE, filled with terrific adventure, of primitive man against monster beast, and of comely cavewoman against unending peril in a world where civilization was not even a cloud on the volcanic horizon. – Summary by Original text
