I thought i'd get this up so you can all get the book.
More wordy write up to follow....
Below is a synopsis from Waterstones:
The Nobel Prize-winner Doris Lessing's first novel is a taut and tragic portrayal of a crumbling marriage, set in South Africa during the years of Arpartheid. Set in Rhodesia, 'The Grass is Singing' tells the story of Dick Turner, a failed white farmer and his wife, Mary, a town girl who hates the bush and viciously abuses the black South Africans who work on their farm. But after many years, trapped by poverty, sapped by the heat of their tiny house, the lonely and frightened Mary turns to Moses, the black cook, for kindness and understanding. A masterpiece of realism, 'The Grass is Singing' is a superb evocation of Africa's majestic beauty, an intense psychological portrait of lives in confusion and, most of all, a fearless exploration of the ideology of white supremacy"
