'A magician and his sone time-travel to Ngoni country and try to change the course of history.'
Source: Publisher's blurb.
The Ngoni people lived in South Africa, in what is now kwaZulu-Natal (created 1994): they were displaced in the nineteenth century in what is called Mfecane (isiZulu), Difaqane or Lifaqane (Sesotho) or 'the great scattering' (English), a period of widespread displacement and warfare among indigenous ethnic groups in South Africa.
