Book recommendations for someone else

Hi! Idk if this is where to come for recommendations but I’m looking for some for my cousin who normally only reads nonfiction but wants to start reading fiction. A lot of my reading preferences are much darker than what he would prefer since he can’t handle horror or thrillers or anything like that so I’m struggling to come up with something for him. He doesn’t read romance either. I brought up the Great Gatsby to him because I did love that one and he said that sounded good so he decided to buy that and try it. He hasn’t finished it though so I’m not sure if he’ll enjoy it or not. So, I guess I’m trying to make a list of books that are a bit lighter but no romance? Unsure if anyone has that and I know it’s kind of specific but this would be a huge help if anyone can give me some recommendations! Thank you so much ☺️
