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.
Yah I read his stuff for years as a young reader and have met him a handful of times and what we get today is very different from back in the day. That said, his book How To Write Science Fiction & Fantasy is still one of the best out there and his short stories are always very well crafted. I always liked his book Songmaster too…too bad. I wonder what happened there.
