Some people on this thread are making some really odd suggestions, like great, difficult works of literature like Thomas Pynchon and James Joyce. The OP is selective about what they like and read, so do you think Gravity's Rainbow will open their eyes? Gravity's Rainbow, a book where there is a club just for people who have finished it. I love Pynchon myself, I think he's a god, but to suggest him on this thread is just ... wrong.
What the OP might like is short stories, Poe, Lovecraft, Murakami, Carver, these are all suggestions I would consider. All short story writers that can be read within a few minutes to a few hours, and are really varied in tone and subject matter.
