The Plains of Passage (Earth's Children 4)

With her companion, Jondalar, Ayla sets out on her most dangerous and daring journey--away from the welcoming hearths of the Mammoth Hunters and into the unknown. Their odyssey spans a beautiful but sparsely populated and treacherous continent, the windswept grasslands of Ice Age Europe, casting the pair among strangers. Some will be intrigued by Ayla and Jondalar, with their many innovative skills, including the taming of wild horses and a wolf; others will avoid them, threatened by what they cannot understand; and some will threaten them. But Ayla, with no memory of her own people, and Jondalar, with a hunger to return to his, are impelled by their own deep drives to continue their trek across the spectacular heart of an unmapped world to find that place they can both call home.
