I'm not entirely sure specifically which 'clueless novels books' you're referring to. There could be various interpretations. It might be about characters who are clueless in certain situations within the plot of the novels. For example, in some coming - of - age novels, the protagonist might be clueless about love, relationships, or how the world really works.
There's also 'The Catcher in the Rye'. Holden Caulfield can be seen as clueless in some ways about the adult world he is on the verge of entering. He doesn't understand the 'phony' aspects of society and is trying to find his place in a world that seems foreign and confusing to him.
Well, a 'clueless novel' might be a story where the protagonist is constantly in a state of confusion. It could be that the author wants to show the character's journey of self - discovery through this cluelessness. Like in some coming - of - age novels, the young characters don't really know what they want at first and the whole story is about them finding their way.
The novel has a great influence on the movie. It provides the basic plot structure. The movie follows the general framework of the novel's story, like the character's growth and development. For instance, the main character's journey from being self - centered to more empathetic is a core part both in the novel and the movie.
