Don't Judge a Book by Its Cover

Recently, I've been looking for books to add to my TBR list for 2025 and, man, are there some truly terrible covers out there, which in a way, kind of fascinates me. I try really hard not to judge a book by it's cover but to be honest, sometimes it's really hard getting over it. I know I'm missing out on some hidden gems by being turned off by the covers. So I was wondering, what are some good books you've read with covers that don't match the quality of the contents?
