Harry Dresden who had so far spent his adult life under imminent death probation from the White Council Wardens (Wizard Police) became one at the end of book seven ( against his wishes and better judgement but needs must when the devil drives, literally) and in this book we see what that really means for him.
Which is soul searching angst as teenagers are beheaded (by the good guys and his colleagues) whilst he battles the usual big supernatural bad guys at a horror film convention and evil entities that feed off fear.
Anyone who has read any of the Dresden files will know that at least two other things will be happening he has to fix, fight, battle for his and other lives which will all piece together at the end. Think Poirot meets Indiana Jones meets Merlin. It is awesome and I really enjoy how Butcher manages to layer hardcore action with genuine emotional depth and philosophical ideas of good and evil right and wrong.
Butcher and Dresden Rock!
