mixing first and third person POV
Question: I'm just curious whether or not it's okay to mix the first person and third person POV in a novel?
Like for example, the story is about the narrator (1st person POV) leaving the country and there are really some important scenes that needs to be tackled by the other characters in the absence of the narrator. Would it be okay to write those scenes in third person POV?
Because I read that some publishers wanted writers to stick to one POV in the entire story or they will not accept it.
It's pretty common for writers to switch to a different POV on occasion. In a story that's primarily told from the main character's POV, this technique may be used to create dramatic irony (where the reader finds out something the main character doesn't). Prologues and epilogues are the most common places where a different perspective is introduced.
Some stories are told from multiple points of view all the way through. In such books, each POV character is more fully developed and acts as the main character of their own story, so the book becomes more like a collection of stories that share a common, overall story.
It is true that there is a bias towards having one main character, one POV, because it makes it easier for the reader feel a close connection with one character. This is especially true in YA or children's fiction.
However, you can't be too rigid about such things. It depends very much on the requirements of your story.
