Ursula and Michael are wary as to why, after so many years away, Simeon has returned but Tom is charmed by him, unaware that Lyzera, herself a sorceress, has infiltrated Simeon's dreams and got him to tell her about the key of bones. This device can lock and unlock the line of twilight, thus preventing more creatures from the Neverside penetrating the world to destroy wizards. To impress Ursula Sieon sets out to find the key, teleporting himself, Michael and Tom to Shanghai where he believes it to be. Unfortunately Lyzera and Varg follow.
