Second book in the Earth's Children series by author Jean M. Auel. Read this a long time ago and remembered really enjoying it. May be a little too graphic for younger readers.
This book has a different (earlier) cover than that pictured.

From the back cover:
"Here is an unforgettable odyssey into a world of awesome mysteries, into a distant past made vividly real, a novel that carries us back to the exotic, primeval world we experienced in The Clan of the Cave Bear - and to beautiful Ayla, the bold woman who captivates us with her fierce courage and questing heart."

Released on Saturday, August 23, 2003 at Senorag's Anything Goes #2 Bookbox in Bookbox, postal release USA.
