The Belgariad Set, Books 1-5: Pawn of Prophecy, Queen of Sorcery, Magician's Gambit, Castle of Wizardry, & Enchanter's End Game

It all begins with the theft of the Orb that for so long protected the West from an evil god. As long as the Orb was at Riva, the prophecy went, its people would be safe from this corrupting power. Garion, a simple farm boy, is familiar with the legend of the Orb, but skeptical in matters of magic. Until, through a twist of fate, he learns not only that the story of the Orb is true, but that he must set out on a quest of unparalleled magic and danger to help recover it. For Garion is a child of destiny, and fate itself is leading him far from his home, sweeping him irrevocably toward a distant tower-and a cataclysmic confrontation with a master of the darkest magic. The quest may be nearing its end, but the danger continues. After discovering a shocking secret about himself he never could have imagined-all in pursuit of the legendary Orb-Garion and his fellow adventurers must escape a crumbling enemy fortress and flee across a vast desert filled with ruthless soldiers whose only aim is to destroy them. But even when the quest is complete, Garion's destiny is far from fulfilled. For the evil God Torak is about to awaken and seek dominion. Somehow, Garion has to face the God, to kill or be killed. On the outcome of this dread duel rests the future of the world. But how can one man destroy an immortal God?
