she is different

Explanation:

In the book, Edna is represented as a woman who thrives for solitude and is pushing away her husband. The book tells a story about Edna who goes against society to fulfill her inner wishes.

She is different from the beginning from her husband and all of her friends, as she is Presbyterian from Kentucky rather than a Creole Catholic. Also, she is different physically from her friends because of her distinctive face and figure.
