The Valley of the Horses is a historical novel by Jean M. Auel. It is the sequel to The Clan of the Cave Bear and second in the Earth's Children series.
This is the story of an unforgettable odyssey into a world of awesome mysteries, a novel that carries us back to the exotic, primeval world we encountered in the Clan of the Cave Bear - and to beautful Ayla, as she leaves the safety of the Clan who raised her and sets out alone on an epic journey of discovery. A hostile land of glacial cold, terrifying beasts and intense loneliness awaits her, and her need for human companionship and love remains unfulfilled.
