Grave Peril (Dresden Files (Audio) #3) (MP3 CD)
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.
