What is the author's style in Play It as It Lays by Joan Didion?

Several points of view are employed by Joan Didion in this novel. The first chapter is told from Maria's first-person point of view. The second chapter is told from Helene's first-person point of view. The third chapter is told from Carter's first-person point of view. Beginning the novel with these three distinct first-person voices immediately draws the reader into the conflict, into the different thoughts of the three main characters.
