I’m been wanting to get back into literary analysis since I’ve stopped doing so after I graduated high school. What are some good, deep, and dense stories with alot to interpret about them?

I recently watched a video about Bladerunner 2049 and the usage of Pale Fire, its theming, and even a few lines of its text for the Baseline Test and it made me want to get back into reading, analyzing and reviewing books, so I wanted to get some recommendations for books that you have to stick with a while to try and understand.
