The writer passed away on Monday morning (08Feb16) at the Marie Curie Hospice in Hampstead, north London after a battle with cancer.

"She had a double mastectomy 40 years ago so she's had a remarkable life considering she had it for so long," confirms her author/journalist husband Hunter Davies.

Their daughter Caitlin Davies wrote on Twitter.com, "Our lovely mum Margaret Forster died this morning, her books will live on."

Forster was a teacher before releasing her debut novel Dames' Delight in 1964. She is best known for her 1965 book Georgy Girl, which was adapted into a film starring Lynn Redgrave and Charlotte Rampling, and a short-lived Broadway musical.

The movie's title song by Australian band The Seekers was a top 10 hit on the U.K. and U.S. singles charts.

Forster wrote a string of novels including The Seduction of Mrs Pendlebury and Diary of an Ordinary Woman, as well as memoirs and biographies on writers including Daphne du Maurier and Elizabeth Barrett Browning.
