The life of an ordinary boy called William is changed forever when the rulers of the Three Realms go to war and his parents are lost in the crossfire. Suddenly he is plunged into a world of monsters and magic, led by the mysterious Ranson, who is an unknown figure from William's past. He tries to discover this in the process of discovering his own powers, and soon ends up being forced into the Resistance; a rabble of freedom-fighters bent on taking down the Three. Will he ever discover his connections to the all-powerful, long-dead Casters, or who this mysterious man is, as he is thrown into the mix with allies; old and new?
