Escaping Earth was the first triumph. Surviving Nyx will be the last… Sixteen-year-old Cassidy Tomei was one of the lucky few airlifted aboard the Wonder to the planet Nyx. This emergency exodus from Earth was meant to bring new hope for the remaining survivors of humankind, but there’s one problem. Humankind isn’t alone on this mysterious new planet. On Nyx, Cassidy is one of many living amongst subzero temperatures and with nothing, but a meager ration of food for every household. When the rations deplete, she flees to into unfamiliar wilderness in search of food, but instead discovers debris from a foreign spacecraft that proves humankind is no longer the dominate species. Soon, everything she knows is at stake and everyone she loves is dead. But she’s got one more battle to fight when she’s taken prisoner within Pelhoi, a concentration camp constructed specifically for humans where hominoid creatures dubbed, “the Achillai” reign supreme. She seeks freedom, but finds romance with someone who might either save her or get her killed.

Cassidy Tomei has done what everyone else said would be impossible. She’s broken away from the maximum security prison, Pelhoi and fled planet Nyx in search of a promise land for her and her brothers to live in peace. After getting news that her mother—who she thought was dead—may still be alive and lost somewhere on the wasteland planet Earth, she’s got no other choice, but to swoop in for a quick rescue and reunite her family once and for all. But getting back to Earth won’t be easy especially since she’s officially an intergalactic fugitive with every bounty hunter in the universe looking to capture and kill her for a major cash reward. Her only hopes lies with Alyen, the half-human/half-alien soldier who’d risk everything to protect and love her through it all. They’d fought tooth and nail to be together before and just might have to do it again since she can’t seem to get her brothers and Alyen to get along long enough to accomplish anything. With battle lines drawn and tensions flaring from all sides, Cassidy just might be forced yet again to decide what’s more important to her. Her love for Alyen or her desperation to protect her family? When you can decide who lives or dies, who would you choose to sacrifice?
