Nine-year-old Allie Finkle has rules for everything and is even writing her own rule book, but her world is turned upside-down when she learns that her family is moving across town, which will mean a new house, school, best friend, and plenty of new rules.

While trying to spare Erica's feelings so she could go to Brittany's birthday party, Allie disobeys one of her own rules and lies.

Con sus relucientes gafas de sol, su lonchera clásica y sus lápices tamborileros, Lupe Lopez llega el primer día a kínder lista para el rock.

En la escuela hay muchas reglas, pero las estrellas de rock no obedecen las reglas, así que Lupe tampoco. Antes de que acabe el día, la maestra le ha quitado todas sus preciadas...
