The Girl in the Road - Monica Byrne

Day 17: Name a book you've read with a hero/heroine who is either poor or from a lower background in status/society.  May be someone who remains in that class or aspires to greater living. (Folk)

 

One of the main characters is from a low caste in India. She eventually becomes free of it by traveling to Ethiopia.

 

I don't know if this is folky enough, but the song fits the book.
