What is the author's style in Petals of Blood by Ngugi wa Thiong'o?

One of the most striking features of Petals of Blood is its narrative style that uses multiple points of view to weave together the stories of the protagonists and those around them. In the opening pages of the novel, events are seen through the eyes of each of the four protagonists. As the novel progresses, an omniscient, third-person voice enters and recounts parts of story. This narrator sometimes comments upon and interprets the events, but on occasion offers a more detached perspective.
