Fun gothicy books

Hi! I’m looking for books similar to some of my favorite child/teenage movies. Particularly, something similar to The Addams Family (not books about them or with them) and The Rocky Horror Picture Show. I know this is weirdly specific but my google search never results in a suggestion that interests me. The “fun” aspect is important. I’ve read quite a few “weird books for weird girls” and haven’t loved them because they all seem very focused on characters who are suffering from
anxiety or being socially weird and I find them too relatable or sad and I want to have a good time while I’m reading. Lol 😂
