Ruled by the murderous King Ulric for too long, its people are desperate for justice. Arthur, son of Uther Pendragon, is their last hope. Now come of age, Arthur can fulfil a longstanding prophecy. And by freeing the enchanted Caliburn from its sheath on Stone Hill, finally the land will have its true king. But Arthur's future is uncertain. Not only does his half-sister Morgana have a vengeful score to settle; those whom he trusts most are also destined to betray him.
