The Legend of Zelda: The Minish Cap (Zelda, #8)

On the day of the Picori Festival, Link and Princess Zelda go to watch the sword-fighting tournament. The winner is a strange man named Vaati, who has come to claim the Light Force which is sealed within the Bound Chest. When the Light Force turns up missing, Vaati turns Princess Zelda to stone! To save his friend, Link needs the power of the Picori Blade, but only a certain master swordsmith can reforge it. Can Link find the pieces of the broken sword before Vaati does?
