Harry Dresden had become depressed since his girlfriend left town. She required a new taste for blood and he became a hermit to try and find a cure. Meanwhile the Queen of the Summer Faerie's looses her Summer Knight and blames his death on the Queen of the Winter Faerie's. Mab the Winter Faerie Queen makes Harry an offer he can't refuse. She will give him his freedom from his faerie god-mother and all faerie debts, if he finds the Summer Knights murderer and clears her name. With this Harry has to deal with the White Council coming to town, to bring him to trial for his misuse of magic and causing a war between The White Council and The Red Court. This book gives us a new twist on Faery lore. Harry was funnier then ever and the mystery kept me on the edge of my seat.
