From the hit New York Times bestselling Dresden Files series: The Warden Morgan has been accused of treason against the Wizards of the White Council-and there's only one, final punishment for that crime. He's on the run, wants his name cleared, and needs someone with a knack for backing the underdog. Someone like Harry Dresden. Now, Harry must uncover a traitor within the Council, keep a less-than-agreeable Morgan under wraps, and avoid coming under scrutiny himself. And a single mistake may cost someone his head-someone like Harry.
