Don't judge this book by the Movie with Daryl Hanna. It is so much better. To me, it is a start on giving insight on why present day people are superstitious or why myths were invented and why religion is a big part of most of the world. I'm on the third book in the series (Earth's Children) The Mammoth hunters, and I look forward to The Plains of Passage. Read Clan of the Cave Bear to get the ground work of the characters. If you like romance novels or erotic novels, it starts to get more steamy at the end of Valley of the Horses, and so far has many steamy scenes in the Mammoth Hunters. :-)
