Books to read when you’re turning 30

I (29f) am looking for some books to read… not really wanting anything that is “life changing” but maybe something that will change a perspective or two. I’ve never really dated anyone, have a good job, live by myself with two cats and have never gone out of my way to do many exciting things. I think I should maybe start doing more for myself as I get older…? Or maybe look into romantic relationships? Idk
