The Land of the Painted Caves by Jean Auel

The end of this book did have more conflict in it than some of the previous books in this series, but I think that it suffers from the same basic problem (and one that the Outlander books also face, to a certain extent): Auel is more interested in how people lived at the dawn of the human race than in telling a story with believable characters and the kinds of conflict that make you want to keep reading. She does a beautiful job with the setting, but it starts to drag in these long volumes.
