So, I'm writing a story and I don't know wtf is my target demographic (MG, YA, or Upper MG). The initial scenes consist of kids of less than eight-year-olds with a not so graphic violence/gory scene; the ending scene will consist of them as teenagers and each of the character have different mentalities after the ending scene/climax. Some will have a YA mentality, some will retain an MG mentality.
I'm thinking I should put this on MG since the violence is not too graphic anyways. What are your thoughts?
