Justice League of America power and glory

Something is coming that has the potential to destroy all of time and space. It seems that Superman is fated to die, and with him, our world. But suddenly, a new hope appears. Rao, the god who brought about Krypton's golden age of enlightenment, has come to Earth, and he's offering to save us all. With Superman vouching for him, it isn't long before Rao and his acolytes are healing the sick and converting the doubtful. But all is never as it seems. At the moment of Rao's arrival, the Justice League was scattered. With Superman by Rao's side, only Batman and Cyborg remain to find the truth. The world needs the Justice League. But can even the world's greatest heroes hope to defeat a god with the powers of Superman?
