What is the author's style in Private Lies by Bobbie Ann Mason?

According to William Harmon and C. Hugh Holman in A Handbook to Literature, realism is "fidelity to actuality in its representation." By this they mean that realistic literature calls for the writer to accurately and truthfully depict real life in their writing. Harmon and Holman continue, "Generally, too, realists are believers in democracy, and the materials they elect to describe are the common, the average, the everyday." Realists are interested in everyday details as opposed to large issues; further, they understand that any fiction truthfully reflecting life will be without linearity or even, at times, without plot.
