From the cover:-
"Remember - you must not let anyone else see it. And do not take it out to look at it yourself."
Tim, Jessica, Simon and Arun fly north. The wind witches, the stump people, the Cruans and the Lord of the Witchwood are combing the countryside searching for them. What is Jessica carrying? Why can no one look at it? And why does everyone want it?
