2013 Nibiru's Shadow It has been two years since Nemesis destroyed life on earth. After beginning new lives on the small planet of Nibiru, Rachael Marks and the crew of the Emperor begin the long task of rebuilding the human race via the precious cargo of DNA they risked everything to preserve. But as the Olmec numbers dwindle, their gaze is once again drawn to earth's refugees, watching the crew as they celebrate the birth of the first children of Nibiru, with a selfish desire to rebuild their own race. The Olmec must be stopped before it is too late and humanity's fragile future is no more. And after Cheang's suspicious death on earth, the full extent of his deception is revealed in Earth's orbit, as China unveils its final secret, Saviour.
