Every 9 years a doorway under Platform 13 at Kings Cross Station opens to an amazing, fantastical island. 9 years ago, the island's baby prince was stolen on the streets of London. Now a rescue party, led by a wizard, a hag, a fairy, and an ogre, must find him and bring him back. But the boy they find is horrid and spoiled rotten. This can’t be the prince! But what about that quiet servant boy who lives under the stairs?
