Meanwhile, in New Beijing, Cinder will become the Commonwealth's most wanted fugitive - when she breaks out of prison to stay one step ahead of vicious Queen Levana.
As Scarlet and Wolf expose one mystery, they encounter Cinder and a new one unravels. Together they must challenge the evil queen, who will stop at nothing to make Prince Kai her husband, her king, her prisoner . . .
