I really enjoy sci fi that focuses on philosophy, questions what humanity is, etc. Harlan Ellison (sometimes his stuff is creepier than any purposefully creepy stories, I had nightmares after reading I Have No Mouth, and I Must Scream, but it was amazing so worth it), Philip Dick (esp Do Androids Dream of Electric Sheep?), Asimov, his short stories are unforgettable, his writing is very 'easy' but the meaning is #deep (although his somehow homoerotic light futuristic detective novels are good too, just different, if you want some Jeeves and Wooster cosmoopera entertaining action then this series is for you. Also he's got a lot of non-fiction books, they're not hard to understand and can be v interesting) and Stanisław Lem.
I like authobiographies, Steven Fry's has literally saved my life when I was 15, Patti Smith's "Just Kids" is very beautiful and made me cry a lot and also interesting if you're into 60s-70s music, Felix Yusupov's memoirs and Stephen Tennant's diary are cool if you're into 1910-1920s and are a good way to see queer people's life how it was back then. And Morrissey.
Salinger's short stories are SO good, The Catcher In the Rye is a but overrated imo.
Also Dostoevsky, Christopher Isherwood (idk, everything he wrote is just perfect, CABARET is based on his diary/novel), Virginia Woolf, Camus, Djuna Barns, Daphne du Maurier's short stories, Wilde (plays esp), Ian McEwan, P. G. Wodehouse, Sue Townsend (her humour is similar to Wodehouse's, she was great), Truman Capote.
The younger authors that I like are Madeline Miller (The Song of Achilles is amazing, it's epic, it's like poetry and will make you cry. Doesn't disrespect The Iliad at all, compliments it v nicely) and Donna Tartt. Tartt's a bit pretentious but very self-aware (a good combination), writes beautifully, has a good sense of humour, her characters are BREATHING AND LIVING and her storylines are so captivating you won't be able to put down her books until you've finished. I recommend "The Secret History", it's my fav book I've read in 2015.
My fav poets are Rimbaud, Richard Brautigan, W.H. Auden, T.S. Eliot, Brodsky, Sylvia Plath, Richard Siken, Keats, Allen Ginsberg.
Wow what a long post sorry guys
