No, because 'nobel book' is not a real term. A novel can be a work by an author who may win the Nobel Prize in Literature, but there's no such thing as a 'nobel book'.
I'm not sure specifically which 'Nobel Book Story' you are referring to. It could be a story related to Nobel laureates and books in some way, perhaps about a book that influenced a Nobel winner, or a story within the context of the Nobel Prize in Literature.
A 'novel' is a work of fiction, usually a long narrative. However, there's no such thing as a 'nobel book' exactly. The Nobel Prize in Literature is given to an author for their body of work which may include novels, poems, plays etc. So, a novel could potentially be part of the work of an author who wins the Nobel Prize in Literature, but 'nobel book' isn't a proper term in this context.
Since I don't know the exact 'Nobel Book Story', it's hard to say who the main characters are. But if it's related to Nobel - winning books, the main characters could be the authors themselves.
