What is the author's style in When the Lion Feeds by Wilbur Smith?

When the Lion Feeds is written primarily in English, but is salted with both Africaans and Zulu dialects. Many words are interjected to lend credibility to the story, such as the terms of respect used by Zulus for white men and women. There are also references made to homesteads as Kraals, and diseases like rindepest in cattle, a disease so deadly that it wiped out entire herds in some cases.
