No one knows anything about them, except that they're always looking over their shoulders. A few days after they arrive in the small town of Waverly, Ohio, it seems like they're settling down. But once they discover a teenager like them, Luke and Luna are on the run again, trying their hardest to save their friends and themselves from an assassin assigned to kill them. But they never know where to go and where to hide. Because wherever the Guardians are, the Hunters are sure to find them.
