The principle of moments

Asha knows she's just another voiceless cog in the vast war machine of the Thracin empire, trapped working on the assembly line of weapons destined to ensure humans like her never escape. When she discovers she has a long-lost sister who may still be alive deep in the bowels of the imperial prison, the decision to risk everything is made for her. Obi knows he has to find the cure to the temporal sickness he caught when he split his soul. But when his path tangles with Asha's they soon realise they are merely pawns in a grand prophecy of fated heroes meeting again and again across space and time to thwart an interdimensional apocalypse. And so they must embark on a quest to the centre of the galaxy, voyaging across the stars in a deadly race against time and tyranny to turn their imminent ending into a new beginning.
