'It is the best knife Colyn has ever seen. He finds it by chance, buried in the potato paddock where he is working with his father, and immediately he knows that he has wanted a knife of his own for a long time. It is special. It is his knife.
'But is it really chance that has led him to its discovery? Colyn soon learns that there is not only beauty in the knife, but magic, too; and with the magic come power and danger. For, with his knife, Colyn opens a doorway into a mysterious otherworld, and here he becomes involved in an adventure more exciting and more perilous than he could ever have imagined.'
