Lya Billings is the greatest female athlete in the world. She competes like a woman possessed, which she is, by the shame of whatever her mother is hiding. When Lya goes in search of her mother's secrets, she is lost at sea, somewhere off the coast of Peru. The only man who can find her -- and the only man who can uncover her mother's secrets -- is Tarzan, Lord of the Apes. And even he may have met his match in The Land That Time Forgot.
