One of my biggest influences as a writer is J. K. Rowling. I grew up with Harry Potter. One thing I absolutely loved was how every single person in Harry's world was so three-dimensional—it was as if each one was the main character in his or her own story and was just making a guest appearance in Harry's story. I strive to do that as a writer. I want every side character to be the main character of his or her own story.
