The Shadowside Trilogy #1 Trion Rising

Those who live in lush comfort on the bright side of the small planet Corista have plundered the water resources of Shadowside for centuries, ignoring the existence of Shadowside inhabitant's, who are nothing more than animals. Or so the Brightsiders have been taught. It will take a special young woman to expose the truth -- and to help avert the war that is sure to follow.
