Books featuring prostitutes?

Hey world4ch, I'm looking for suggestions of books featuring prostitutes as protagonists or prominant characters. I'm not looking for erotica; I was hoping for something that focuses more on the life experiences (emotional or otherwise) that people who sell sex must go through.

Examples would be Memoirs of a Geisha (understandably not about a prostitute) or Kushiel's Dart (closer to what I'm looking for, but it dealt more with politics and less with sex). Any suggestions? :)

Geisha, a Life
by Mineko Iwasaki or something

but geisha aren't close to prostitutes!  maybe you're interested in books about women's journeys that aren't so feminine that you'd be criticized as gay for reading.  I don't want to read some sappy love story about a couple living on the prairie, but if it's about a potential slut, I'm interested!
