Hannah and Amanda Given were among the few survivors when their world collapsed in a sheet of white light. Now, only months after being pursued across the country by government forces and the Gothams - a renegade group with similar powers - the Silvers discover that their purpose on this unfamiliar Earth may be to prevent its complete annihilation. With continually shifting alliances and the future in jeopardy, the Silvers realize that their only hope for survival is to locate the other refugees - and determine whether they can be trusted or not.
