Jacqui Graham said that Howard died yesterday at her home in Bungay, England. No details as to the cause of death were immediately available.
Howard's whirlwind life saw her write 15 novels, leave three marriages, model, act, broadcast, and much more. Many of her books were critical successes, but she was best known for "The Cazalet Chronicles," which followed the tangled lives and loves of several generations of an aristocratic household in the run-up to World War II.
"She walked away from a marriage, which was a very advantageous one, to do what she wanted to do, which was write. She lived her life in a way that she wanted to live it in, in a way that women at that time just didn't have the nerve. She had the nerve."
Born in 1923, Howard had little in the way of formal education, but she read voraciously - "huge amounts of Shakespeare and other classics," Graham said. "When she ran out of stuff she wrote her own things."
"As she put it herself, Jane was a bit of bolter," Graham said. "She didn't put with up things she wasn't going to put up with."
Howard's work included "The Beautiful Visit," a coming-of-age novel structured around World War I, and "Mr. Wrong," a collection of short stories centred on the lives of 1960s London women, and "The Cazalet Chronicles," a series of books which would follow the eponymous upper-crust dynasty through from the carefree thirties, into World War II, and beyond.
