The witches have bent the land of Yutara to their will, but no one knows it yet. No one but the Emerson Stone. These witches aren't the sickly green, wart-faced witches from bedtime stories. They hide in plain sight. And they're everywhere. When Ace Halder finds a mysterious stone on Grandpa Marty's ancient Earth ship, the twelve-year-old learns of a power he can neither contain nor understand. For it may be Yutara's last hope against the rising darkness. Now, Ace is left with a choice. Run and hide? Or traverse the world's darkest roads at one last chance to save Yutara.
