Query: The Plains of Passage, Earth's Children Volume 4

Continuing the saga of Ayla and Jondalar, Jean Auel brings to vivid life the Ice Age, its inhabitants and their way of life. Her descriptions of the vegetation and animals of the time is spell-bounding, and I absolutely love her descriptions of the people of the time. She describes their way of life, diet, and the way they interact with other groups in mesmerizing detail. If you have read the first three of the Earth's Children books, this is a must read.
