Igraine, who turns twelve tomorrow, dreams of becoming a famous knight. But today, like most days, life at the family castle remains… rather boring. Until the nefarious nephew of the baroness-next-door shows up. Greedy Osmund's got a dastardly plan to capture Pimpernel Castle and steal the singing magic books that belong to Igraine's mom and dad.
