what is the age that you identify as an adult
For the widest audience, youâll generally want your protagonist to be on the oldest side of your readership that your plot will allow. That means a 12- or even 13-year-old hero for MG, and a 17- or 18-year-old for YA (just remember your hero canât be in college yetâthat would push it into the ânew adultâ category).
