It has been almost a year since Peter and Julia first visited the land of Aedyn and, faced with the harsh reality of their father s remarriage and two new horrible stepsiblings, they re beginning to wonder if it was all a dream. As they run away from home one evening, they fall into a half-frozen river and find themselves back in Aedyn---but this time they ve accidentally brought along their stepsister Louisa Aedyn is deserted; the people taken captive and forced to work as slaves at the foot of a volcano on a distant island. As Peter and Julia wonder what has happened to their beloved country, a giant falcon appears and takes them to this island, the very place from which the Lord of Hosts saved his people centuries ago. The three children must find a way to save the prisoners and bring them back to Aedyn, but the earth is trembling and the volcano is starting to smoke. They re running out of time."
