The Cornerstone Craig C. Mccabe First edition

A cornerstone is the foundation on which a world is built. If you know the secret, you can travel to other worlds through the cornerstones. Rathsmus has had a difficult life. His parents died when he was young and he was sold into slavery to a sorcerer. He later learned that he has the potential to become a sorcerer himself. He has had limited success as a sorcerer until he meets five witches who teach him true magic. Eventually, Rathsmus is befriended by a world of dragons and together, they fight the evil that has plagued the dragon world for one thousand years and Rathsmus' world more recently. The worlds of the cornerstones collide in a war to eradicate the evil forever.
