Book three of the Chronicles of Ooligilbie. When the light of Ooligilbie begins to fade, something is terribly wrong. The Magic Pool lies dim and restless, its song nearly gone—and something dark is stirring beneath its surface. Called back by Flash, Ally and Ciro return to a world they love, only to find it changing. The music that once protected Ooligilbie is breaking, and without it, the shadow will rise. With Granny, the dragons, and a mystery long hidden in the heart of the Pool, they must uncover what has been forgotten… and restore the song before the light is lost forever.
