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.
As a young reader in the 80’s, Sleator was a gateway into sci-fi. My lifelong friend and I (both in mid-40’s) still talk about him when we chat about books.
