What is the author's style in Where the Lilies Bloom by Vera Cleaver and Bill Cleaver?

The novel uses modern language to tell the story of the Luther family, but there are regional patterns of speech that reflect the way the people of the Smoky Mountains speak, and differences in speech patterns also reflect the different levels of education that the characters have. Since Mary Call is the narrator of the novel, the language of the story is her voice, and there is an effort to reflect her dignity in the way in which the story is told, while maintaining honesty. Mary Call never refers to her own fright, but she will tell the reader what others said to her, that her eyes were big or she is bawling.
