"Under Platform 13 at King's Cross Station there is a secret door that leads to a magical island . . .

It appears only once every nine years. And when it opens, four mysterious figures step into the streets of London. A wizard, an ogre, a fey and a young hag have come to find the prince of their kingdom, stolen as a baby nine years before.

But the prince has become a horrible rich boy called Raymond Trottle, who doesn't understand magic and is determined not to be rescued.
