Teriel (The Warrior's Stone) The Lightstone Chronicles, Book 1

Book 1 of the Lightstone Chronicles
For a thousand years, the Acan Empire has ruthlessly dominated the land, its black power assured by cruel sorcerers and merciless assassins. In the midst of the darkness, a glimmer of hope is about to appear in the most unlikely of places: deep in the caves under Mount Horgathe. Destiny has chosen a 15-year-old slave, born and raised in a mine, to fight for his people's freedom. The young man's name is Teriel.
