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 loved Singularity when I was in middle school. It was a beat-up copy with the cover falling off in the school library. I was doing some community service in my old school about four years later and took a peek and saw that I was the last person to have checked it out. So being the dumb teenager I was I took it. I told my mother about it ~15 years later and she ended up getting me two copies of the book for Christmas that year. One was a recent print in paperback and the other was a first edition hardback signed by William Sleator.
