I'm sorry, but without more specific information about Manuel and Silvana, I can't tell their full story. There could be many Manuels and Silvanas with different stories.
I'm not entirely sure what 'capitulo simpsons pulp fiction' specifically refers to. If 'capitulo' means chapter in Spanish, perhaps it could be about a chapter related to 'The Simpsons' that has some connection to 'Pulp Fiction'. Maybe it's a fan - made crossover idea where elements of the two are combined in a particular chapter or story.
Since I'm not well - acquainted with their works, I can't accurately say what the common themes are. But generally, in novels, common themes could include love, friendship, self - discovery, or social issues.
Another theme might be the subversion of expectations. We expect the Simpsons characters to be in their normal, comical situations. But if there are elements of 'Pulp Fiction' involved, like unexpected violence or complex moral situations, it subverts what we know about the Simpsons. So, subversion of expectations could be a theme.
I'm not specifically familiar with works by 'Silvana Black and Blake' in the novel area. There could be many emerging or niche authors. You might try searching for them in specialized independent bookstores or online book platforms that focus on new and diverse authors.
