Recitatif by Toni Morrison

Twyla and Roberta have known each other since they were eight years old, when they were thrown together in a girls' shelter. Inseparable then, they lose touch as they grow older, only to meet again later at a diner, a grocery store and then at a protest. Recitatif keeps Twyla's and Roberta's races ambiguous - we know that one is white and one is black, but which is which? And who is right about the race of the woman the girls tormented at the orphanage?
