I like the idea of having one big book to read in a year. I have done that with East of Eden and the Glass Bead Game. Both of which are meaty epic books. I tackled them initially as a rebellion against the short attention span world we live in. Even in reading niches, I all too often see reading challenges that set # of book goals. I think it's absurd to claim that someone has read 20 books in a year that are short, verses one long book. The former is often applauded while the latter is not.
Karamazov has been one that I've been wanting to read all my life, so maybe I'll attempt it in 2024 myself.
Non linear writing is a struggle for me, but I try to challenge myself with it. I'm currently reading The Waves by Virginia Woolf which is incredibly abstract but beautiful. I assume Gravity's Rainbow to be similar. But it's a thick book too.
