Books with a smart female protagonist

As the title says I’m looking for books with a smart (like knows how to fight; has a photographic memory; has a really high IQ; etc.) female protagonist. I would love a book where there is no focus on romance and I really don’t want a book that in the end only centers around some hot man.

I would love something morally grey or a woman with a dark past who is now fighting for good and people are surprised by how smart she is. I also love female villains as long as they have some moral compass. I really hope I explained it well enough and that someone knows a book like this!!
