The Paris Wife is a historical novel written from the point of view of Hadley Richardson, Ernest Hemingway's first wife. In general I don't like historical fiction because authors often take too many liberties with the actual facts. McLain, however, has done a very careful job in her research, so that only the dialogue between characters is fictional.
Ernest Hemingway had such a strong personality that each of his four wives tended to disappear behind him after they married him. It is nice in this novel to see Hadley's perspective of their famous Paris years: her dislike of expatriate morality, her fear that her husband would leave her, her ability to recover from their divorce.
