Book #54 was Grave Peril, the third book in Jim Butcher’s Dresden Files. The back of the book reads:
Harry Dresden’s faced some pretty terrifying foes during his career. Giant scorpions. Oversexed vampires. Psychotic werewolves. It comes with the territory when you’re the only professional wizard in the Chicago area phone book.
But in all Harry’s years of supernatural sleuthing, he’s never faced anything like this: the spirit world’s gone postal. All over Chicago, ghosts are causing trouble–and not just of the door-slamming, boo-shouting variety. These ghosts are tormented, violent, and deadly. Someone–or something–is stirring them up to wreak unearthly havoc. But why? And why do so many of the victims have ties to Harry? If Harry doesn’t figure it out soon, he could wind up a ghost himself . . .
Harry’s really gotten himself into a pickle this time. There’s not much of Murphy and the cops in this one, but he manages to get himself into enough trouble anyway. And when it’s all said and done, it’s really just beginning… I think this book really marks a gear change in the series.
