So, I've long thought my current WIP fit into the category of young adult literature. The MC is eighteen and in a gap year between high school and college. However, she drinks, smokes, and, at some points in the novel, though it isn't very detailed, she has sex. I would argue she's a fairly regular teenager with normal teenage experiences. But, some readers of the YA genre are especially young and it's been brought to my attention that it isn't appropriate to market this manuscript as YA for that reason.
I figured I'd pose the question here because I've been going back and forth for the last few days: have I written a YA book or not?
