The narrator of a novel could be the protagonist of the story, a third party, or a voice-over. In most cases, the narrators were the protagonists of the story because this allowed the readers to be more involved in the plot and better understand the characters and events in the story. However, sometimes there might be a third party or a voice-over to narrate the story. This would make the story more objective and comprehensive, allowing the readers to better understand the background and truth of the entire incident.
