I'm in a quandry. The novel I am currently working on has two distinct plots that end up merging as conflict between the two factions escalates. I started my novel in 1st person as I wanted it told from the main characters POV. But now I'm finding that I am really leaning toward the 2nd plot/faction of the book being in 3rd person. Would it be within the 'rules' of writing to jump back and forth. I would do it in seperate chapters. So one chapter would be in 1st person from the main character's POV. Next chapter changes to 3rd person and a different faction of the book, different main character. Too weird? Or would it be okay?
