Lucky Star is book six in the Dark Universe setting by Jason Halstead
Brindal and Ellena are Terrans lured to an alien world with the promise of a new way of life and equality among the races. Potential for all, regardless of race, gender, or belief. The reality was far from the truth, especially when Ellena showed her first signs of mutation.
Mutated beings- those whose latent powers are awakened with the resurgence of alien energy brought about by the return of the Ampythean race- are hunted and taken away. Their fate is unknown, but nobody has heard from them since.
As Ellena's powers grow and she fails to control them, they are left with no choices but to throw away their lives and run. They have to find a way with no weapons and no friends to get off the planet before the Vagnosian army catches them. If they can manage that, then they can hope for a better future amongst the stars.
