Well, I try to read as much as possible, and though the only young POV character (of 3) in my current favorite novel, Fifth Season by N.K. Jemisin, is a very young "Orogene", I find that I prefer teenage protagonists, as apposed to, say, fully-aged protagonists. That being said, I'm not seeking to write a YA Fiction Novel (people seem to so commonly be predisposed to not want to read YA Fiction), but it seems like in most cases (not all, but most), teenage protagonists are typically in YA Fiction. I'm attempting to write a high-fantasy novel (with the main protagonist actually being relatively powerless compared to some other characters), but even if Ernis(the protagonist) doesn't have the same "overwhelmingly powerful abilities," as they would be from his perspective, that some other characters like Maurel and Wilhelmina have, I'd like him to be realistically useful in situations involving combat somehow. How would I go about writing my novel in such a manner?
