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.
I don’t think I’ve ever come across anyone else mentioning that book. I had to read it for a ‘Science Fiction as Literature’ course in college and it certainly fit the bill. Such a beautiful work.
