For Harry Dresden, Chicago’s only professional wizard, business, to put it mildly, stinks. So when the police bring him in to consult on a grisly double murder committed with black magic, Harry’s seeing dollar signs. But where there’s black magic, there’s a black mage behind it. And now that mage knows Harry’s name.

Could a werewolf be loose in Chicago? Common sense says no. The grisly evidence says yes. So does Harry Dresden. And with his weird connections, he should know.

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.
