Easy, warm, light-hearted books

I'm trying to get over a pretty ugly breakup and haven't been feeling like myself so wanted to get back into reading. I noticed I can't seem to focus very well anymore, and every new book I've opened seem to have some kind of plot around cheating and it just breaks my heart all over again. I'm not looking for any specific genre (except avoiding anything romantic obviously), but I just want to be able to read something and enjoy it again. I like dark humor, mystery, historical/historical fiction, fantasy.. you name it. Just looking to fall into another world I guess. I also speak French so open to English or French recs :) thank you
