So yes, generally speaking, you have your protagonist's age the same as the targeted age of the reader (or higher, but not by too much). Since this is YA, the age range for a MC is roughly 14-18. The younger the protagonist, the younger the content (usually). My story calls for a thirteen-year-old, and this isn't necessarily a "younger content" YA novel. Violent (detailed) action scenes. Even if there are no prominent sex themes, drugs are a reality, and this novel is set in Newark. Now, the environment in which this boy grew up had him mature faster than your usual kid, added to the fact that he had to grow up surround in a world of "superheroes" (I use the term loosely). He definitely doesn't act like the average immature thirteen-year-old boy, but he's not the genius protege with no flaws, either. What I've been wondering is whether a novel of violent conflict, both physically and mentally, will be downplayed by the young age. I could always play it safe and make him older, but if that was what the plot required, then I would have done that to begin with. His sister is closer to the targeted age (17) and is heavily involved in the plot, yet the boy is the one narrating from his POV. Having a dual POV would be anticlimactic, since the sister is an unwitting antagonist. Do you think readers could still relate to a MC this young? Or am I overthinking it?
