Dhillan lives in a world where at any moment she could be required to ruthlessly kill her 'twin'. Another 'Earth' identical to her own has been discovered and now people from both planets can travel back and forth between the two. With an apparent bloodlust for their identical 'other's on each planet it's natural that both have become that of a battle field. But for Dhillan and her 'twin', Ember, they're destined to rebel against nature and their controlling governments, harnessing the legacy their mothers' left them, to make peace with oneanother. Now they're being hunted by their own people whilst stifling their urges to hunt themselves.
