This study focuses on neuro-sociological impact of apartheid as depicted in lifestyles and lives of characters in Damon Galgut’s novel The Promise. It studies his sharp portrayal of a white family in post-apartheid South Africa. It chronicles the experiences of a white, affluent family who runs a small farm over the course of several decades.
