Driven into exile by his own people, a young Tor stuggles to survive alone in a periious prehistoric world. But beyond mere existence, Tor struggles for answers to the questions that have plaqued humankind for eons — why are we here? Is violence the only answer? is there more to life than suffering and survival?

His quest will take him deep inside a mysterious mountain — a dark land filled with strange peoples, evolving animals, and death at every turn. And while Tor must fight these battles alone, he will find some new friends along the way -- all the time coming a step closer to what it means to be truly human.
