Instant In The Wind [EPUB ebook] 

In early 1749 a white woman and a black man are stranded in the wilderness of the South African interior. She is an educated woman, totally helpless in the wilds. He is a runaway slave. They know only each other. At first their relationship is guarded, poisoned by the black and white in them both. But hesitantly there emerges between them a fellowship that engulfs their most private selves, as they face the long trek back to civilisation.
