Under Platform 13 at Kings 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. 'This kind of fun will never fail to delight.' - Philip Pullman.
