"Jean Auel researches like crazy before she writes these books. Her characters are very believable and the way she incorporates the facts of her research into her story does not make it seem like you are reading a textbook. You find yourself thinking about what happens next to Ayla when you are not reading this book. It is easy to look up at the clock and loose 4 hours because you are so involved in the story."
