The threat of war hangs heavy over the Twin Kingdoms.
Inquisitor Melyn, in possession of an ancient source of unimaginable power, journeys though the northlands in a merciless bid to overthrow King Ballah. Benfro, captured by a travelling circus and drugged into compliance, must perform like some trained animal for the amusement of men. With each passing day the dragon's chances of ridding himself of Magog's malign influence recede.
Yet all is not lost. Errol Ramsbottom, left for dead, follows Benfro's trail. The young dragon holds the key to rescuing Errol's beloved Martha, trapped in Gog's terrifying world. Only together can Benfro and Errol hope to cross to the other realm to save her.
As the ancient spell that split Gwlad begins to unravel, unlikely alliances form. The old order is crumbling - what will happen when the barrier between the two worlds finally falls?
