Scout has been running her entire life. She, like her tribe, is chasing their ancestors' vision.

The youngest and fastest of the Kin Circle's lookouts, and a rising leader in the Stone Age tribe, Scout is the first to see the new homeland promised to her people.

The sixteen-year-old has spent years listening to her Eldest Grandmother’s stories about the fertile valley; her tribe has journeyed for generations in search of the elusive paradise. But wonder quickly turns to fear when they reach their new home: the valley is already occupied by alien visitors, strangers unlike any people Scout has ever seen.

Scout discovers she is the only member of the Kin Circle who can communicate with one of the strangers, Ori, also a teenager. Ori has been taken from his troubled home world and brought to the valley against his will. The strangers claim they pose no harm, but Ori reveals their sinister intentions and supernatural powers to Scout.

Together, Scout and Ori try to overcome his captors’ deception ... and find themselves growing closer each time they meet.
