The children are waiting at a railway station to go off to boarding school, when they suddenly experience a peculiar sensation, and find themselves whisked back to the magical world of Narnia. Gradually familiar landmarks give the children clues that they are standing in the ruins of Cair Paravel--their once great castle. Slowly, and rather unwillingly, the children realise that a long passage of time has taken place since they left Narnia. But time is not the only thing that has passed in Narnia. Narnia is no longer a land of talking animals, of dryads, fauns and dwarves. A cruel king now rules the land, a Telmarine named Miraz. These are the "New Narnians." Deep Magic calls the children back to Narnia, and it's their task to save the kingdom for the "Old Narnians" and deliver it to its rightful king, Prince Caspian.
