The Pen Doesn't Lie

Jamie is used to putting pen to paper. She's been doing it for years, and has a slew of novels to show for it. For the most part, she's left alone to write, but this is the first time someone has knocked on her door, insisting they are one of her characters, and demanding to know how she knows what she does. Armed with only her pen, her notebook, and her cat, Inkwell, she finds out just how much of their own lives her characters have taken on outside of her novels.
