When mortal enemies Veronica Lopez and Heather Simms get hit by a bar code scanner while fighting over the last copy of Queen of Twilight, it takes them a moment to realize that they aren’t in a New Jersey bookstore anymore. In fact, they’re in the novel. Too bad they don’t realize it until after they accidentally kill the book’s heroine, Princess Arabelle, aka "The One." Only The One can restore light and peace to the land of Galma, long held in thrall to the evil Twilight Queen. Now Vero and Heather have no choice but to try to save Galma from the Twilight Queen. But can the two girls find their way to the end of the story and home again without destroying Galma—or killing each other?
