What is the author's style in Africans by Sheila Kohler?

The story uses a first-person narrator, Mkatie's sister. In first-person narratives, the story is told from the point of view of one character, who gives readers information based on what the narrator has seen or heard. In this case, the narrator talks about her sister's life. Throughout the story, the narrator seems very dispassionate, merely reporting events. Even the most emotionally charged scenes, such as the narrator's retelling of Mkatie's husband's pedophilic acts, are described in plain, understated terms.
