Great, but it is part of a collection of short stories by him that most of us have read and bought the books that they are in... Since it is Harry, Maggie, and Mouse it may give us a glimpse of what Dresden family life will be like... So it should be a little better than the usual crumbs tossed our way to further the story..
I've said this for a while now... That is why I wish for his sake and his fans as well that he wrap up the series, instead of needing five books to do it, make it two.. Then get into the BAT..
At one time I would have vehemently disagreed with you; however, time and one's expectations change. Plus, I've read other extended series which would have benefited from "getting to the point" rather than meandering down the road; becoming a travelogue or introducing new and uninteresting plot twists along with pointless characters to kill off, and in general just being a bore. I'm sure a lot of us could name two or three series that fit the last sentence above.
I can't see inside of Jim's head; none of us can, but I do wonder how clear the path forward is for him with Harry Dresden. Sure, Jim has an outline; but the description of it sounds to me to like a series of a very basic ideas like, "Harry wakes up without the ability to do magic", rather than a detailed list of how each novel should progress. Maybe it would be better for Jim to reexamine what he really needs to do to bring Harry's story to a fitting conclusion, rather than committing to a concept he came up with due to his misunderstanding what his writing teacher said to him about thinking about how to develop and finish Storm Front, almost twenty years ago.
Maybe reading Peace Talks will make me change my mind, but I have a feeling that even if it exceeds my expectations I'll feel like the story should start heading for the finish line rather than just turning another corner in the road.
