Rank high, save your family - lose yourself. Shy but brilliant Phaet ("Fate") Theta has spent fifteen years living a quiet existence in a lunar colony founded by scientists generations before. But when her mother is imprisoned and accused of treason, Phaet must save her sibilings from a grim orphan's future by joining the Militia, a league of faceless enforcers. To survive Militia training, Phaet must rely on her wits, resilience, and fierce ambition - and on Wes, with whom she feels kinship if not exactly trust. But the higher Phaet climbs through the ranks, the more she discovers the world she's known is a lie.
