When a plague turns people into monsters, the only safe place left to live is the Ora, a spaceship lingering beside Earth's moon. Aboard are the specimens of the next generation, modified genetically to develop powerful, supernatural abilities, which they must use to exterminate those infected by the plague and stop the apocalypse. From the day Eos Europa was created eighteen years ago, she's cared about little else. But despite being a formidable opponent with a rule of never backing down, her lack of a supernatural ability disqualifies her from becoming a soldier. Stripped of the title she's worked a lifetime for, Eos feels she's lost everything. But that changes when soldiers start disappearing. Just seconds after landing on Earth, they begin falling off the Ora's radar without a trace. Desperate for answers, the Ora's leading officer deploys Eos as their replacement, regardless of her deficiencies-and in the end, it's not her deficiencies that stop her. It's the realities she faces, which cause her to question everything about who she is, where she's come from, and how the apocalypse really began, leaving her to decide whether she'll continue to play the puppet she was created to be, or disappear like everybody else.
