Any interesting fiction books with demonstrably smart protagonists?
No idea if this is the place for this question but I first came across LW after I read HPMOR a long time ago and out of the blue was wondering if there was anything with a similar protagonist.
(Tho maybe a little more demonstrably intelligent and less written to be intelligent).
I think Traitor Baru Cormorant is excellent, with really excellent writing.
The protagonist is a smart utilitarian with hidden goals. She isn't infinitely smart, though; people beat her. And the book has an insane downer ending, so if you're worried about that don't read.
There are two sequels with a fourth supposedly (eventually) to come; the author has clearly read some rationalist-adjacent stuff like "The secret of our success."
