My current idea for a novel is a very, very difficult one to accomplish correctly. In the small town of St. Ashby, a teenage boy spree-kills seven of the town's residents. It's the aftermath of the horrific shooting this is concentrating on, and how it effects the others who live there. My MC was vaguely friends with the boy who did it, so I was wondering how this would effect her mentally. Another character -- a primary school teacher -- has an eleven-year-old who was one of the survivors, so I need to research more about child psychology. If there are any experts willing to help me with this, I'd be very grateful.
