If I'm being honest, I think a lot of teens have these feelings. So, introducing this element more explicitly into my story feels exciting, and terrifying. Those of us who are not teens are understandably uncomfortable with a teen's capacity to do real harm to another human being. But when I was a teen, my own dark sides terrified me and obsessed me. So, venturing down this road with my protagonist interests me. How do we manage to come through the other end of those huge feelings of rage and those destructive tendencies? How do we explore them, harness them, process them? What happens when we try to ignore them or avoid them?
In the end, I think this story will be infinitely stronger when I take it in this direction. But I'm worried. I'm pretty confident the teen readers will have no problem with this darker vision. I wonder if the adult gatekeepers will be able to handle it. I wonder, frankly, if I will be able to handle it. Time, as Virginia Woolf would say, to strangle the angel in the house.
