I'm not sure who 'Fabiana' specifically is in 'Pulp Fiction' as there is no character named Fabiana in the movie that I recall. It could be a name that is being misassociated with the movie.
Since I'm not familiar with the 'fabiana science fiction story', it might be unique due to its setting. If it's set in a completely new and uncharted type of universe, with its own laws of physics or social structures, that would set it apart from other sci - fi works. For example, some science fiction stories are set in post - apocalyptic Earths, but if this one is set in a different kind of apocalypse, like on a different planet, that would be unique. It could also have a unique narrative style, perhaps using a non - linear storytelling approach which keeps the readers on their toes and makes it different from more traditional linear science fiction stories.

I don't know who the author of the 'amor eterno novel' is. There could be many novels with this name and without more specific information, it's difficult to determine the author.
I'm not sure specifically as there could be many novels with 'amor eterno' in the title. It might be about eternal love, perhaps following the story of a couple who face various challenges but their love endures through time.
