I chose Gore Vidal, although Last Exit to Brooklyn also looks interesting. I like to know a book's been banned at some point, and The City and the Pillar by Gore Vidal ticks a lot of boxes in that respect. Apparently he had to write under a pseudonym for years after it was published, due to refusals to review his subsequent work, and he noted that 'shocked' was the least extreme reaction to it from critics... It was still a crime to have gay sex in the UK in 1948, when it came out, and indeed until 1967.
I know about Gore Vidal from the fact he wrote the original script for Caligula and I’ve watched some interviews with him but I’ve never read any of his books. That’s largely due to the fact no one I knew talked about him until I found out about Caligula. My stepfather disliked him due to him being very liberal in his outlooks and was a fan of his rival, William Buckley, instead.
