"There was a time when everyone was happy. A time when everything was advancing. People had families, homes, lives. But then came the earthquake. They shattered the land, tearing apart families. Towns and cities crumbled, leaving the world in pieces. That's all I remember of the Old World. The horrors burned into my mind. Now all that remains are the tribes. And the Hunters. And my sister." Surviving in a corrupt world fifteen years after the earthquake that destroyed the country, sixteen-year-old Arys lives in one of the tribes, always changing location due to the Hunters. Nobody knows where they came from, or why they hunt the survivors, keeping everyone in the tribes in constant fear. When Arys discovers that her twin sister, thought to be dead, also survived the destruction and is living amongst other survivors in a safe haven known as the Compound, Arys leaves her tribe to find her. Heading towards the Compound, Arys journeys with her best friend Kai, not knowing how much her life will be thrown into a plot she knows nothing about.
