Maybe some of you actually know of good titles in this type. Girl in question is 12, but is more into stuff for somewhat older girls, so I would not recommend her very safe, kid stuff, as that will not interest her. Also, no faggotry please, the world is pushing that shit on all of us all the time, so it's best to not open another venue for it. Needs to be available in English, and the more obscure stuff I might not be able to get for her, I assume it is at least somewhat limited what books I can get here.
She is also into horror movies, if that helps.
Thank you to any of you fine gentlemen for any recommendations.
Not usually my wheelhouse but I have come across a few, you may want to use translation sites for some of this:
Kill the Villainess: the protagonist is Reincarnated into the body of a villianess of a novel who is destined to be executed as a traitor in the story. She tries to escape this by killing herself but fate itself won't allow it and the main three characters in the novel who were supposed to be disinterested with her now are suddenly interested.
It's a completed work and a more dark story focused on escaping a pre destined fate. There is romance in it but kinda revealed at the end so rather not spoil.
