In the wake of her parents' separation, Polly, a fifteen-year-old wannabe writer, comes face to face with her inner dragon, a truculent, impatient creature named Scrum who is a talented but frightful critic of her writing. With the help of Ms. Patience Whitford, a literary dragon trainer and leader of a global writing guild, Polly faces the almost impossible task of going beyond her good ideas to finish a publishable piece of fiction. All the while, Polly and Scrum become entangled in a dangerous scheme that threatens the future of every writer on the planet.
