What is the author's style in Personal History by Katharine Graham?

As a memoir, Personal History is told in the first person from Kay Graham's point of view. In her 70s, Kay Graham retires as publisher of the Washington Post, wants to keep busy and decides her life may be interesting to general readers. She is dissatisfied with the coverage her parents and husband have received in print, and she devotes much of her attention to their lives and careers. Graham is educated at the University of Chicago and works for a small San Francisco newspaper as a reporter before joining her father's Post. Because in the 1940s it is unthinkable for women to lead a business, her husband Phil is brought in to assist father and succeed him as publisher. Kay is content to be a typical (albeit upper-class) suburban housewife until Phil commits suicide, when she is suddenly thrust into the all-male world of publishing. She learns the ropes slowly and painfully and becomes one of the most powerful women in America, standing up to and taking the wrath of the Nixon administration. Graham has known a vast array of important and interesting people, whom she sometimes too briefly characterizes. Personal History is intended for general readers, although those interested in 20th century history and/or politics will benefit most from it. Graham struggles to show how she grows out of her parents' and husband's dense shadows to preserve and improve upon the legacy she passes on to her son Don. She admits her life is unique and unrepeatable, and she is correct that it is a story worth reading.
