The Library of the Dead

Maybe a YA novel? This book takes place in Scotland, where there are a lot of haves and the have-nots are really just barely eking out an existence. There’s a weird library and some supernatural stuff going on. Our plucky hero is a young woman of color managing a lot of stuff--poverty, supporting her family, learning magic, threats--while trying to learn a bunch of stuff and figure out a bit of a mystery. Very engaging.
