You can't keep a good wizard down - even when he wants to stay that way.
For  years, Harry Dresden has been Chicago's only professional wizard, but a  bargain made in desperation with the Queen of Air and Darkness has  forced him into a new job: professional killer.
Mab, the mother of  wicked faeries, has restored the mostly-dead wizard to health, and  dispatches him upon his first mission - to bring death to an immortal.  Even as he grapples with the impossible task, Dresden learns of a  looming danger to Demonreach, the living island hidden upon Lake  Michigan, a place whose true purpose and dark potential have the  potential to destroy billions and to land Dresden in the deepest trouble  he has ever known - even deeper than being dead.  How messed up is  that?
Beset by his new enemies and hounded by the old, Dresden  has only twenty four hours to reconnect with his old allies, prevent a  cataclysm and do the impossible - all while the power he bargained to  get - but never meant to keep - lays siege to his very soul.
Magic.  It can get a guy killed.
