Most kids have an active imagination. My imagination has stayed strong into adulthood, and I’ve funneled that creativity into a successful writing career. I write history, both fiction and nonfiction, because although your school history classes may have been boring, the past is not. My goal is to bring the past to life in all its myriad of colors.
