The Mystery

An action-packed fantasy adventure series from the authors behind Sabriel, The Keys to the Kingdom and The Fixers.

When Grandma X is put out of action by an accident that may or not have been caused by The Evil, it's up to Jack and Jaide Shield to help their father recover a lost Golden Card from Portland's strangest landmark: The Rourke Castle.

Negotiating secret passages, talking parrots and animated suits of armour is all in a day's work for the troubletwisters, whose Gifts are steadily coming under control. But agents for The Evil are everywhere, including one apparently masquerading as an old and trusted friend.

In this gripping new series of fantasy stories, international best-sellers Garth Nix and Sean Williams combine to create a world that will have boys and girls aged 10+ absolutely gripped. Ideally suited to fans of Percy Jackson and Harry Potter.
