Example Input: I have been in love with this book (and the entire series) since I started reading it when I was eleven, five years ago. Ayla is the ultimate heroine, yet she is totally human, real, and touchable. Auel's extensive research allows her to paint a stunning picture of prehistoric earth. Her characters fit this picture perfectly to tell the amazing story of one young girls life. Malinda Brow
