Mrs. Hunter's fourth grade class is putting on a play; but Allie's theatrical hopes are crushed when she doesn't get cast as the princess.
Instead, Allie is cast as the evil queen. As opening night approaches, Allie learns its not the size of the part; it's the size of the heart that really matters.
Four children separated by vast distances all undergo the same ritual, watched by cloaked strangers. Four flashes of light erupt, and from them emerge the unmistakable shapes of incredible beasts: a wolf, a leopard, a panda, and a falcon. Suddenly the paths of these children, and the world, have been changed forever.
Enter the world of Erdas, where every child who comes of age must discover if they have a spirit animal, a rare bond between human and beast that bestows great powers to both. A dark force has risen from distant and long-forgotten lands and has begun an onslaught that will ravage the world. Now the fate of Erdas has fallen on the shoulders of four young strangers... and on you.
