I don't understand the logic behind goodreads "More like your 2019 books"-recommendations. I mostly read thriller, crime, fantasy and occasionally some manga/comics.
Goodreads doesn't recommend ANY thriller, crime, manga or fantasy books, BUT it does recommend self-help (I read 2), love (I read 2), a book written in 1898 (?!?) and a book on web design (??????).
I'm very confused…
