The Valley of Horses is a historical fiction novel by Jean M. Auel. It is the sequel to The Clan of the Cave Bear and second in the Earth's Children series. Plot summary The book starts off from the events at the end of The Clan of the Cave Bear detailing the life of a young Cro-Magnon woman named Ayla who has just been exiled from the Clan, the band of Neanderthals who had raised her from early childhood. Ayla now searches for her own people, whom the Clan refer to as "the Others". In a parallel narrative, Jondalar, a young Cro-Magnon man of the Ninth Cave of the Zelandonii, accompanies his impetuous younger half-brother Thonolan on a traditional rite of passage called the Great Journey. In these episodes, we learn of the Cro-Magnon's paleolithic nature religion, centered on the worship of the Great Mother of All, and follow their adventures and sexual exploits. It is also through these episodes that the animosity, verging on hatred, between the Others and the Clan (whom they refer to derogatorily as "flatheads") is introduced. The Others have repeatedly persecuted the Clan, taking land and resources, but justify it by classing them as animals. However, over the course of his adventures, Jondalar starts to question this prejudice, noting that no other animals have fire, tools or communicate intelligently, nor are they actively hated or attacked-as-sport by his people. Ayla, alone and ritually ostracized from the only people she has ever known, travels steadily from the Black Sea peninsular home of her former tribe north for around half a year until finding the book's titular valley sunk deep into the windy landscape of the periglacial loess steppes in Ukraine. Worried that she might never find the Others, she begins to prepare for winter. Finding a suitable cave and many conveniences in the valley, she establishes a comfortable but lonely life there. Her desire for companionship leads her to tame a filly whose mother she had killed, naming her Whinney. She also takes in and treats an injured cave lion cub, which she names Baby. Through her love, she is able to train Whinney and Baby to assist her with hunting and gathering. Ayla is also able to give and receive love from these animals, saving her from her loneliness. In the course of their journey, Jondalar and Thonolan have met women and hope to settle
