This isn't a "look what I'm writing, is it good?" post, I promise. I’m new here, but I read the sticky post first. Still, let me know if I've done something wrong. Some background: 3 years ago I wrote a short story. When I went back to revise that short story, a new character introduced itself and took over. That short story is now an almost-finished novella of 30,000 words. My characters are angels, namely, The Angel of Death and Cupid (they have completely different origins, I know). I didn't know at the time that you actually could write stories about angels, or that it had ever been done before apart from Milton, so it really is my own take on it. My question: regardless of how well it’s written (I’m working on that), I know that because I am not writing a story about everyday people, I run the risk of making it sound silly and unbelievable. If I can’t make readers believe these characters could actually exist, they simply won’t believe the story itself. This is a serious story (drama/horror); I don’t want people to laugh at it because the characters are not human. I’ve read it over and over and even I have trouble taking it seriously at times. It just sounds fake and childishly make-believe, no matter how well I word it. Would having it in 1st person from the POV of the Angel of Death be adding to this “false” feeling about it? What about having the MC talk to the reader as a collective "humanity"?
