Third person could be helpful if we're describing a chance that's supposed to happen when a character isn't noticing it. But even sometimes in those stories, I feel like first person is a stronger choice whenever the story allows for it.
Here's an excerpt from my gender change ebook, Mer-Made:
But I saw something funny in the reflection of one of the glass panels of the fish tanks - a mop of curly, red hair. But Serena had dark hair. I had red hair of course, but I kept what little of it there was closely cropped. So...whose hair was that?
What would that sound like in third person?
But he saw something funny in the reflection of one of the glass panels of the fish tanks - a mop of curly, red hair. But Serena had dark hair. Peter had red hair of course, but kept what little of it there was closely cropped. So...whose hair was that, he wondered?
It clearly still works, but it feels a little weaker, doesn't it? What do you think? Do you prefer gender change stories to be in 1st or 3rd person? Do you have a strong preference on the narration styles of other story genres?
