What is the author's style in Wide Sargasso Sea by Jean Rhys?

The novel is divided into three parts. In the first, Antoinette is the only narrator. In the second part, Rochester takes over, but his narrative is interrupted briefly by Antoinette. In the third part, the English nurse Grace Poole is the narrator until Antoinette regains the narrative voice. This first-person narration is significant because it lets the reader see the world through the subjective gaze of flawed characters. In Parts I and II, Antoinette reveals her own naivety by relating her story.
