Theo Wicklittle is a scrawny teenage boy who lives on a small farm with his widowed mother Sara and half-sister Molly. While working in a field, he comes across a sword buried in the mud. As he looks over it he cuts himself — the smallest of nicks — leaving a drop of blood upon the dull blade. It is then that he finds himself in the presence of a grubby, dishevelled young woman, named Nya Waymourne. Long ago, during an ancient war, Nya was cursed and imprisoned in her own weapon by an evil wizard. Now, she and Theo must set out to free the remaining eight heroes and ultimately lift the curse upon them all before the wizard's demonic servants find them.
