Maia and the Xifarian Conspiracy by S. G. Basu

What if everything you believe is a lie?

Maia has spent most of her life trying to run away from her past. When a chance encounter lands Maia in a dubious peace initiative, she has to walk down a road she had hoped never to tread. Little does she know that the real truth about her long-deceased mother is somewhere down this path.

But before she gets to that, Maia will discover true friendship, face an unimaginable evil, and fight her deepest fears to save the world she loves.

A planet on the brink of extinction. An enemy from the dark side of the universe. Only one girl and her secret stand between them.
