Eref is about to die. He sits at the End of Light World, accepting his stoning execution one rock at a time, until the impossible happens: the ground opens up beneath him, and he drops down into the unknown. There, he meets Caer, a kind-hearted girl from Dark World who saves his life. Together, the pair forms an unlikely and illegal bond that not even the strongest hatred can break.
