14-year-old Avia's whole life turned upside down 4 years ago when a deadly, rabies-like disease started spreading everywhere. Mass panic, government shutdown and every other negative affect has happened to the world since, and she's was sure she was doomed. Even when the disease stopped spreading a couple years later (and she's somehow still alive), the world is still corrupted and hopeless. But Avia and her younger sister Mayla still won't give up on each other, even with their friends and parents dead and the world they ever knew before completely gone, replaced with a harsh post-apocalyptic one. Avia still refuses to give up her hope and survival and will stay alive. . . at all costs.
