My bookworm DD loves biographies and historical novelizations. She eats up books about Helen Keller, Susan B. Anthony, Sacajawea, etc. She also loves the American Girl series and learns some history and about other cultures from them. She really seems to identify with female figures and strongly prefers books about girls and women.

She loved the Little House books and still reads her favorite parts over and over again.

I agree, there are lots of positive messages for kids in these books. I do talk to DD about them, too.
