This really isn't a recommendation as much as an observation over the course of my Linux exposure. I've purchased a few Linux books in the past, but at best they were a little-used reference. (much more useful as a dust collector) A majority of the time (easily over 95%+ of the time) I found better answers with a little Internet sleuthing. Many times, books quickly become outdated.
on books i found this one readable https://nostarch.com/howlinuxworks3 and if you know where to look you can get it "gratis" . the book online version of linux from scratch will also give you half a clue .
