In 'Grave Peril', wizard-for-hire Harry Dresden confronts an unprecedented challenge: ghosts are wreaking deadly havoc across Chicago, far beyond the usual spectral mischief. As violent and tormented apparitions sow chaos, it becomes apparent that something—or someone—is deliberately stirring them to cause destruction. With the specters’ violent outbreaks eerily connected to Harry himself, he must unravel this deadly mystery before he is reduced to one of the angry spirits terrorizing his city, or worse, becomes a specter of his former self.
