Auel's latest book was just released in March. I read the first five in the Earth's Children series and loved them. The amount of research Auel conducted for these books is incredible. I now have the latest book and am in the process of reading it. The series is about Ayla, a woman of Neanderthal/Modern man Europe, who survives and thrives, first alone, and then with her companions--three horses, a wolf and Jondalar. Love her books!
I started reading his books back in 1976, during the American Bicentennial. I think there were eight books in the Kent Family Chronicles. It was like stepping back into history. I enjoyed reading about the generations.
