Which came first for you?
In writing my YA science fiction project, I had a very clear vision of the world my character existed in before I ever knew the character herself. As a result, I think that finding her voice has been more difficult than if I had started with her first. The world she lives in is clear and detailed and nuanced. The world was my first love, the character came later. Finding this character, her voice, her wants and ultimately her story has been the major work of my revision. You have to have both or you really don’t have a finished product.
