A world is dying. Its only chance for survival lies with a Great Spell that nobody knows how to perform. What they do know is that they need three objects of power- a cup, a sword, and a crown. Strange things are happening in Eade, a peaceful English town that is home to a boy called Nathan. Nathan has dreams of a world that is contaminated by magic. He gradually realizes that he is dreaming of a real world, a world completely different from his own. The Grimthorn Grail is a cup that once belonged to the Thorn family that is said to have strange powers. The only remaining Thorn descendant wants the cup back and is trying desperately to prove that the original sale was illegal. As Nathan's dreams become more and more real and he learns about this other world, he realizes the fatal problems that it is facing. The cup comes from the other world, he is sure of it, but he also thinks that it was sent to his world for safekeeping until a need to use its powers arose. Where does the cup truly belong? Can the world be saved?
