In all his years of supernatural sleuthing, Harry Dresden has never faced anything like this: the spirit world's gone postal. These ghosts are tormented, violent, and deadly. Someone-or something-is purposely stirring them up to wreak unearthly havoc. But why? If Harry doesn't figure it out soon, he could wind up a ghost himself.
