I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
Irene Nemirovsky, there’s an ébullition of emotions inside me whenever I read one of her books, it’s one of the rare cases where I don’t seperate the author from the artwork.
