Wolf Brother (Chronicles of Ancient Darkness)

6,000 years ago, the land is one dark forest. Its people are hunters and gatherers. They know every tree and herb and they know how to survive in a world steeped in enchantment, menace and powerful magic. Until an ambitious and malignant force conjures up a demon; a demon so evil that it can be contained only in the body of a ferocious bear; a demon so hungry for death that it slays everything it sees; a demon with the potential to destroy the world. Only Torak and his wolf companion can save the world.
