Harry Dresden animates a Tyranosaur to fight six evil Necromancers.
Let me repeat that. Harry Dresden animates a Tyranosaur to fight six evil Necromancers.
The book is Awesome in a Hatbox. And I'm not spoiling anything or giving it away, because they put it on the cover. More of the metaplot is revealed. Harry is given yet ANOTHER complication in his already complicated life, and his relationship with Thomas and his dog also advances. Murphy is absent, but still very present in the stakes involved (since the main challenge Harry faces is a threat to Murphy).
But the most interesting aspect of the whole thing is a) All you ever wanted to know about Bob the Skull and b) The advancement Harry has to the office of Warden, which puts the oppressed, potentially into the role of oppressor.
