Publisher's Synopsis
When Jon and Tania attend a costume party at a museum full of ancient arms and armor -- relics that have been through bloody battles, or worse -- it doesn't surprise either of them to discover a ghost lurking in the shadows. But this particular ghost is on a mission, and if Jon and Tania don't help him, he just might become the warrior he was when he was alive, and that means trouble -- and danger -- for everyone involved!
