was told to ask here. any book suggestions for an anon coping about Shingeki's shit ending? Looking for a book that
>has fairly simplistic lore for a brainlet
>no tolkien shit (no elves, dwarves, aliens, only humans)
>Has some jaw dropping twists
>High stakes
>Minimal magic mumbo jumbo / science mumbo jumbo
>Nice heavy themes (I like existentialism)
I enjoyed books like I, Claudius so I do enjoy political shit (meaning to check out Wolf Hall). Also enjoyed Game of Thrones when it was good. Although I did not like Dune because I couldn't get into the characters emotionally. Currently I'm working through Book of the New Sun and Red Rising, although I am not enjoying the weird color classism system of Red Rising. Feels a bit goofy. I enjoyed The Eternal Champion but thought it wasn't in-depth enough.
Book suggestions?
