Storybound (Stormbound, #1) by Marissa Burt
In the land of Story, kids go to school to learn to be the perfect character: a brave Hero, a trusty Sidekick, even the most dastardly Villain. They dream of the day when they will live out Tales written just for them.
But when an ordinary girl named Una Fairchild finds herself Written In to Story, she discovers that the magical land is threatened by a dark secret. As she digs deep into Story's shadowy past, Una realizes that she is tied to the world in ways she never could have imagined—and it may be up to her to save it.
Dog Gone note: This is a fun and funny story about how heroes become heroes, princess become princesses, and villains become villains through training for fairy stories. Then there is Una who was written into the story and who is not confined to her assumed role, but wants to be a hero instead. If she could just figure out how she got into the story in the first place and why she is there.
