Binyavanga Wainaina, Kenyan author and journalist, in the winter 2005 issue of Granta:
Always use the word 'Africa' or 'Darkness' or 'Safari' in your title. Subtitles may include the words 'Zanzibar', 'Masai', 'Zulu', 'Zambezi', 'Congo', 'Nile', 'Big', 'Sky', 'Shadow', 'Drum', 'Sun' or 'Bygone'. Also useful are words such as 'Guerrillas', 'Timeless', 'Primordial' and 'Tribal'. Note that 'People' means Africans who are not black, while 'The People' means black Africans.
Never have a picture of a well-adjusted African on the cover of your book, or in it, unless that African has won the Nobel Prize. An AK-47, prominent ribs, naked breasts: use these. If you must include an African, make sure you get one in Masai or Zulu or Dogon dress.
In your text, treat Africa as if it were one country. It is hot and dusty with rolling grasslands and huge herds of animals and tall, thin people who are starving. Or it is hot and steamy with very short people who eat primates... Make sure you show how Africans have music and rhythm deep in their souls...
