"One million years ago, young caveman Tor fought to survive alone in a perilous world. Driven into exile by his own people, Tor embarked on a quest that took him deep inside a mysterious mountain where man fought beast for dominance over the changing world. Confronted by strange tribes and evolving animals, Tor experienced the adventure of a lifetime only to struggle with the questions that would plague humankind for eons to come: Why are we here? Is violence the answer? And is there more to life than suffering and survival?"--Jacket.
