Teen Gothic

I hope this is allowed, I'm not trying to advertise myself so I won't even name my store. After 9 soul sucking years in the tech industry I decided to do something dramatically different and I'm opening up a Gothic themed bookstore. Music will of course be a huge part of my store, selling records and playing goth music 24/7 at the store. And of course, books ranging from fantasy to true crime to horror and everything else. I wanted to ask: what would you like to see in a Gothic bookstore?
