Books like The Clan of the Cave Bear & The Valley of Horses

This series is by far my FAVORITE set of books ever written. Auel just creates a totally believable story - you can envision these people living, discovering and evolving with every turn of the page. I think it read it for the first time back in 1990 but I would have to say that I have re-read the series everytime a new book comes out and then even a couple times in between. I would recommend this book to anyone although as you get into the second book and beyond there is some adult content that may be inappropriate for younger eyes/minds. It is all done in good taste so to speak but I would just warn parents so they can decide what is okay for their kids or not.
