Book recommendations?

hello everyone!

I (20F) need help getting back to reading, but the issue is, there is nothing that truly grabs my whole attention. I really like thrillers and mysterious type of books, I like a bit of romance but not something that is too much of sexually explicit. I have tried reading YOU before and I really loved it a lot but what made me drop it is how many times sexual fantasies and action was happening ( ﾟεﾟ；)..

I hope to really get some good recommendations!

please just give me a brief background of like a teaser of what the book is about! thank you!
