I finished "The Diamond Age" by Neal Stephenson and "Hail Mary" by Andy Weir, now I'm working on "Ulysses" by James Joyce.

And just... holy shit, how much more remarkably difficult it is to read Ulysses as opposed to the other two. The Diamond Age is a good bit of sci-fi, if a little dense, while Hail Mary felt like reading a childrens story for how easy it was. Now Ulysses is so massively dense, with no quotation marks, constantly referencing Shakespeare, speaking in 4 different languages thus far, while ricocheting from thought to thought, scene to scene like a bullet fired inside a closed metal chamber. It's a massive shift.
