Kybel is a tribesman of a primitive society. When he sets off on what should have been a simple hunting trip, his life is changed forever. A massive storm keeps him from returning to his people. While struggling to get home, he experiences a near fatal fall that means certain death-until he is rescued by a mysterious advanced society. Under the care of this alien civilization, Kybel's life is dramatically altered as he learns of technology, philosophy, and a modern way of life that he never dreamed existed. Upon returning to his own people, though, he faces a difficult choice. Does he stay with his tribe and teach them all he has learned, or does he choose a different path? He feels pulled to return to the advanced civilization that not only saved him but now also feels like home, partially due to the woman he has come to love. Unknown to him, his decisions will soon bring him face to face with the greatest challenge of his life: a fight against an alien race that threatens to destroy all he cares about, in this world and others.
