What is the author's style in The Bean Trees by Barbara Kingsolver?

Up until chapter five of The Bean Trees, the narrative point of view is split between a first-per­son narrator and a third-person narrator. In the chapters dealing with Taylor Greer, Taylor tells her own story, but the chapters that focus on Lou Ami Ruiz are narrated in the third person. After Lou Ami and Taylor meet in chapter five, Taylor's point of view takes over and the third-person narrative disappears. Taylor's first-person narration fleshes out her character and puts her at the center of the novel. The third-person narrative in Lou Ann's chapters has limited omniscience, which means that the nar­rator is able to see into the minds of only some of the characters. In these chapters, the narrative reveals Lou Ann's feelings and motivations, although there is some distance between Lou Ann and the reader. When the two narrative points of view merge in chapter five, a sense of harmony is created, as the chapter's title suggests. Taylor and Lou Ann's decision to make a home together becomes reflected in the unified point of view.
