Igraine, who turns 12 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. Complicating matters, on the eve of the siege her parents misspeak a spell and turn themselves into pigs! (How inconvenient.)

Igraine's birthday wish has come true, and the challenge is bigger than she ever bargained for. Will she face her fears and find the courage to save the day - and the books?
