My name is Jim Butcher and I write stories.  Ask me anything, Friday at 12:30pm Mountain Time on Reddit!
12:39 PM - 31 May 2018

Just a guess on my part, but Jim must be very, very close to wrapping up Peace Talks; or maybe he's finished and will announce it officially today, seeing as Jim must know he will be asked "how much longer?"

What I really want to suggest is that if your able to do so, now would be a good time to ask Jim some deep questions that he might answer.  Something less obvious and direct as "who fixed Little Chicago?" or overasked like "Why did you choose Chicago to set the story in?"  I have to work Friday afternoon so I'm counting on you guys to ask some interesting questions only members of this forum could come up with.  Sorry I wasn't able to post this earlier, but I just got in on a late flight from Los Angeles and am about to hit the sack.     

Jim has said that Peace Talks will feature a great deal supernatural violence.  My question isn't about who you want to see die; though you may want that too, it's about who would you like to see go out in a knock down drag out bloody fight to the finish? 

If it's a wizard, perhaps we will see them throw a death curse that unleashes mayhem on their antagonist or antagonists.  I'd like to see a death curse that doesn't have any subtlety to it; unlike Quintus Cassius' curse against Harry or the one Margaret LeFay laid on Lord Raith, something really spectacular and messy, perhaps from the Merlin.     

There has been a trend of the Dresden Files novels getting longer, though Skin Game had a lower word count than Cold Days.  Also, if you compare the Cinder Spires book with the first book of the Alera series; well, there is no comparison.  "The Aeronaut's Windless"  a much longer and more involved story.  Now we know Jim has had various life issues which have contributed to Peace Talks taking so long to get done, but does anyone else think (because I do) that Peace Talks is going to be a more complex story (or have more stories to tell within it) than what we usually get from a Dresden Files novel?  I mean Skin Game had a pretty basic story idea; a heist story where Harry was forced to work with Nicodemus and both of them would try to double-cross one another.  There were of course unexpected complications, but I'm just talking about the main plot of the novel.  Many of the early novels had easily identifiable A and a B plots.  For example, in "Blood Rites" Harry is trying to stop an unknown foe who is using an entropy curse to kill people on a porn movie set and at the same time he's organizing a strike team to find and kill Mavra.  These A and B plots are often related to each other in ways that Harry didn't understand, but again, I'm just talking about the basic plot structure, not how various elements might be blended into the overall story arc. 

I'm thinking that in Peace Talks, Jim has more balls to juggle than in perhaps any other Dresden Files book before it.  If you've read the preview first chapter you know that So if you didn't read the spoiler there are two issues that Harry will be involved with in some manner.  However, that leaves many other potential complications that in themselves may become their own, let's call them C and D plots.  Not to mention that the first issue in the spoiler is a rather open-ended one.  It's not a straightforward idea like, I want you work with Nicodemus and “I expect you to skin them alive” or "They've taken our daughter."  We can only guess where this story element may go and there is really nothing in the earlier novels that might give us more than a tiny hint of how this could play out.

Jim has said that Changes, Ghost Story and Cold Days could be described as an internal trilogy within the series, that turns it in a new direction.  I would argue that Skin Game should be added to this list and call it a quadrilogy within the overall story arc, because SG settles the issue of the "parasite" inside Harry's head we learned about in Ghost Story and it demonstrated that Harry; though at times with some difficulty, was learning to control the Winter Knight's mantel.  So we had Harry's life deconstructed in Changes and it has taken until the end of Skin Game to see that a new life is now possible for him.  So now that Jim has fully turned the ship around that means Harry will face more complicated situations to untangle and I think they begin in Peace Talks.

Just to give one example, we don't know what the future holds for the White Council and its most prominent members.  In Changes it almost seemed like a civil war was possible or that a coup was about to take place.  I suspect Jim was setting up serious complications and likely endings for one or more characters on the Council.  I won't be surprised if we see one or more of those complications or endings happen in Peace Talks.  That is just one possible avenue Jim might explore.  Think about all the other possible complications that might arise, and even if only one or two come to a boil, you've got a bigger and hopefully engaging novel for us to (eventually) read, and one that takes some effort to tie together.  All that said, I'm hoping that really soon we will read that Jim has finished or as he has often done in the past, he announces that only the denouement is left to write.   

PS: If you would like to make a guess at likely complications or plot twists we might encounter, feel free to do so.  I think it's about time we start compiling a prediction list and later see who came closest to the mark.       

So Jim said we can expect some drama for Mister as we near the end of the series.  (At Salt Lake Comic Con last week.)  Speculate what that might mean for Mister and Harry.

In one of the Q&A's Jim did at Dragon Con, someone asked Jim if he ever considered writing a short story from Donald Morgan's POV.  While Jim didn't completely dismiss the idea, he said such a short story would be something of a downer because Morgan's personal history was very dark.  Specifically, Jim said Kemmler killed Morgan's parents and the rest of his family.  Anastasia Luccio rescued Morgan.  Unfortunately Jim didn't give any other details such as how old Donald Morgan was at the time or why Kemmler went after Morgan's family. 

I never realized how far Jim had worked out Morgan's backstory.  I wonder if sometime in a future book Anastasia will fill Harry in on Kemmler's history; I mean in more detail than Bob did, and her personal history of dealing with him and his followers.  Kemmler may be gone for good; or maybe not, but I'd bet dollars to donuts his legacy will play a major part in future events.

After reading the latest short story featuring Luccio in Dodge City (A Fistful of Warlocks), I started thinking about Anastasia Luccio and other White Council members personal perspectives versus that of Harry's.  So Anastasia was born in the late 18th or early 19th Century.  Let's say she joins the White Council around 1830 or a little before that.  After a few years she is introduced to older members of Council, perhaps even a Senior Council member or two.  Consider that with the possible exception of Ancient Mai, every other SC member is from an older generation than the members we see today. 

Now stop and think about your own life and stories you heard as a child from either your grandparents or other relatives who where older than your mother or father or maybe even from a next door neighbor who was around the same age as your grandparents.  Think particularly about those stories about what life was like when they were children.  So the living memory of other people you have been exposed to may go back sixty or seventy years before you were born, occasionally more if you had any particularly long lived family members who told you a story or two that really impressed you.  I'll give you an example from my life.  When I was a child; maybe eight or nine, my family went to a wedding in New Mexico, I think near Silver City.  I grew up near Los Angeles, CA so this was something unusual.  Before the wedding my mother met with some of her cousins.  One of them showed my mother an photo album with pictures of people, none of whom I knew, though my mom recognized several.  There was one very old picture; think Teddy Roosevelt era, of a young man that my mom asked about.  I think the only reason she asked was because the photo was so old.  Her cousin identified this man as a great uncle on her father's side, someone she had never met, but a person her grandfather had talked about a great deal.  He had been a soldier during the First World War and had died in his mid to late 20's, during the 1920's, but it had been the war that had killed him.  She told us that he had been a victim of a poison gas attack and he never really recovered from it, it slowly destroyed his lungs over time.  It was a horrifying story and the person who told it hadn't actually witnessed it, but the story her grandfather told her made an impression on her and later on me.  That's one small example of living memory being passed down from one generation to another, actually several generations.

Think about the people Anastasia met when she became a Warden or even earlier than that.  Some of the older European Council members she met not only had lived during the time of witch burnings in Europe, they may have witnessed someone being burned at the stake. (The Witchcraft Act of 1735 in Great Britain made in illegal to claim someone had magical powers or was a witch.  Though witch hunts continued sporadically for sometime after that in other places.)  It's one thing to read about something like this in a book, now imagine having a friend, colleague or family member who could describe to you the crowd of onlookers, the executioner and the victim or victims.  Then imagine this living witness telling you about the sound of the crowd made and the crackling of the fire, the screams of the victim(s), the smell of burning flesh and the feeling of pure fear that you could be next.

Harry has an academic appreciation that wizards were once burned as witches.  Luccio, Ebenezer, Arthur Langtry and other older members of the White Council didn't experience this directly, but they knew people who did.  I think this explains; at least partially, why Council members are disturbed by Harry's openness to openly proclaim himself a wizard; and some of his other more flippant behavior, even if most of society thinks that he is a crackpot.
