Ever since Grey Alexander's parents disappeared five years ago, she's had one goal--to keep herself and her younger sister Rin alive. But surviving in the North American Wildlife Preserve isn't easy, especially for the unconnected who can be shot on sight by border patrol robot drones. Through the guidance of their eccentric old neighbor Mrs. March, Grey and Rin get through by smuggling contraband into the Mazdaar government's city zones. But when Grey is captured by the merciless General Evangeline Yurkutz and is forced to become bait for her mother and father, she questions everything she thought she knew about her life in the Preserve, her missing parents, and God. Is it possible Jupiter isn't uninhabitable? And could this planet, whose sky swirls with orange vapors and where extinct-on-Earth creatures roam free, hold the key to reuniting her family?
