Under Platform 13 at Kings Cross Station is hidden a quite remarkable secret. Every nine years a doorway opens to an amazing, fantastical island.

Nine years ago, the island’s baby prince was stolen on the streets of London. Now a rescue party, led by a wizard and an ogre, must find him and bring him back. But the kind prince has become a spoilt rich boy, who doesn’t believe in magic and doesn’t want to go home. Can they rescue him before time runs out – and the doorway disappears for ever?

‘This kind of fun will never fail to delight’ Philip Pullman
