The year is 2522. Anna is a Remnant-a secret Christian in a world that has banned any form of religion. She is also an astro-geologist working with her Robot, named Z, for the Planetary Science Commission. The PSC has worked for 200 years to find alien life on another planet, and finally, after two centuries, a primitive lifeform has been discovered. Faced with the reality of evolved primitives on a forested moon, Anna begins to question all she has ever believed. Anna and Z travel to the newly-discovered moon in search of answers, but a terrible accident leaves them stranded. Faced with dangerous natives and unfamiliar surroundings, Anna and Z stumble upon a conspiracy that has universal implications. Will Anna discover the truth about the moon and its inhabitants? Can God still move within a culture that has abandoned Him?
