Queen of Sorcery book two of THE BELGARIAD

The master Sorcerer Belgarath and his daughter Polgara the arch-Sorceress were on the trail of the Orb, seeking to regain its saving power before the final disaster prophesized by the legends. And with them went Garion, a simple farm boy only months before, but now the focus of the struggle. He had never believed in sorcery and wanted no part of it. Yet with every league they traveled, the power grew in him, forcing him to acts of wizardry he could not accept.
