There is a group of books called "Earths Children" written by author jean m auel. Its my favourite story of all time and its all about a girl called ayla. They even made a film of it starring daryl hannah as ayla. There are 5 books,
The Clan of the cave bear
The valley of horses
The mammoth hunters
The plains of passage
The shelters of stone
