How did popi battle with the issue of self identity?

Popi is Niki's beautiful daughter, a living example of what is so broken and stupid about apartheid. She is physical proof that (contrary to prejudiced historical opinion) black people and white people are perfectly compatible by nature. The child is lovely, with light black skin, blue eyes, and fair hair. She also represents the dual nature of the nation, but in union instead of apart. She is also caught between both worlds: nthe world of not looking totally black and not looking totally white.
