If you like the movie Out of Africa and like to know more of the writer of the book upon which the movie was based, and the love affair you will like these 4 books.
You should also visit her home in a suburb in Nairobi, Kenya. This suburb is now renamed Karen in honour of her. It is an exclusive area. When I visited about 4 years ago, we also had lunch at her home in a converted restaurant.
Poser name her lover.
