Born in Iran to British parents, Doris Lessing grew up in Africa. "The Grass Is Singing", her first novel, is about a love affair between a married white woman and her black servant. The book was published in 1950, and it took courage for anyone at the time to write about such intense race issue. We congratulate her on winning the Nobel Literature Prize.
