Her father's secrets saved her. Her mother's secret poisoned her. Her secret may kill her. Her world is dying, poisoned and ravaged by war, and there's only one way to survive. Sixteen-year-old Valora steps up to lead her people in an evacuation, scattering them among the stars in a desperate hope to preserve Zerian life. The new world where they seek refuge—a place that harbors a powerful and mysterious energy, and native lifeforms that are far from welcoming—proves to be no less treacherous. But Valora soon realizes that the greatest danger her people will face is the one they brought with them. The locket her father gifted her before she left carries the secrets about what happened to her world, about what happened to her mother—whose mysterious death still troubled her—and about the enemy that is closer than she ever imagined. Valora must make a heartbreaking choice in order to save not only the lives of her people, but their souls as well.
