I have decided for the epilogue of my novel, Under the Darkened Moon, to switch POVs. This is, of course, still a rough draft but I think it makes sense even though the entire novel has been 3rd person limited from the viewpoint of the main character to this point.
I want to pull back and go 3rd person omniscient to reveal things that are ok to reveal now that the story is over. Particularly the thoughts of the novel’s secondary character more in depth as well as putting the reader in the mind of a character who has been mentioned and referenced but never introduced until now and who has good reason to be introduced.
I wouldn’t consider changing POVs like this within the novel proper and suddenly but for the postscript, I think it will be ok and add to the story.
