In a city that’s just beginning to recover from the devastation caused by the Battle of Chicago, Harry Dresden is finally pulling himself together as well. He’s ensconced in his own personal castle, healing his various wounds, and training an eager new apprentice. The last thing he wants is any trouble. But, as history has consistently–and quite annoyingly–shown, what Harry wants is rarely what Harry gets. It starts with a visit from Harry’s most powerful frenemy, Gentleman John Marcone, Baron of Chicago. He needs Harry to assist in the redemption of an underling who’s looking to go straight. And since Harry does kinda sorta owe Marcone for saving his life once (stupid honorable debt!), it’s not a request he can refuse. He’ll just wish he had. Because this little favor is going to drag Harry into a fight he doesn’t want on behalf of a lowlife he doesn’t trust against an enemy more powerful and pestilent than he ever could’ve expected: an insatiable, demonic foe whom Harry himself may have created when he wiped out the vampires of the Red Court so long ago. Before, all it wanted was blood. Now it wants the entire world . . .
