"Jondar is the ultimate civilized Cro-Magnon, a well-muscled, artistic, spear-throwing Cary Grant. And it is Ayla...who invents oral sex, horseback riding, a new technique for making fire, and a better way of dragging the kill back to the cave. But despite all this 'The Valley of Horses' is great fun to read. Jean M. Auel has created ancestors who do us all credit."
