It seems to me Jim is very good about getting all his anthologized work into his own exclusive anthologies. So I would have to assume this could be the main piece in the next one, but that it will be available in print at a future date. I don't think he is close to having enough for another volume, though.

It's 2 hours 46 minutes, and Jim reads it himself.... no Marsters.

but if it is like Bigfoot - that WAS eventually printed...  in Brief Cases ? I don't mind if he gives them a head start and some exclusive time, if he does release print at a later date.   Remember he had a smaller house print Backup first, then it was rolled into Side Jobs. Jim's been good about eventually getting his work out to us without having to buy other people's fiction too, if we choose not to. 

EDIT: What's fascinating is that Butcher has drawn a strong correlation between size and power, at least with the Fae. We've discussed before in other threads, I think Maggie Sr spent most of her pregnancy in fast or slow time Nevernever zones to guarantee Harry would be starborn. Her own height aside, I've long wondered if Harry's near-outlier height is an expression of Butcher's Fae correlation.

Perhaps, but doesn't Harry's mother's spirit say something along the lines of Harry has his father's height? Maybe Harry is not unusual amongst Dresden men.  I seem to recall Bill Walton and Patrick Ewing both having sons who played in the NBA who were roughly Harry's size

The cold wouldn't bother Harry, he is the Winter Knight, besides this is the guy who took cold showers for years in his little basement apartment in the dead of winter in Chicago.

You know, those cold showers never made sense. You can get those little solar bags campers use to heat up at least a little water. Put it out the window with a line coming in. Thermal absorption is not high tech. Blowing out circuits can be done with an EMP, and maybe magic is similar. EMP won't do crap to the bags.

Usually at puberty, yes.

But that age varies, person to person; anywhere between 8-13 is considered a "normal" age for girls in the USA (9-14 for boys).

Puberty itself then lasts 2-5 years, and I'd expect powers to manifest nearer the middle or end of puberty, than at the beginning.

HOWEVER: it's very possible Maggie won't have any powers at all:  in the Dresdenverse, "salic law" suggests it (mostly) follows the maternal line, and Susan hadn't the slightest bit of magical talent.

Mostly, yes... but wasn't there a WOJ that Maggie Sr.'s mom was a vanilla human - she got it from Daddy Eb

Unless the cover is totally unrepresentative (Exhibit A Harry Dresden’s Hat) the threat is going to be in the Toot size range, so that if that is indeed Toot’s Sweet, Lacuna it is the eighteen inches height range plus and set after Cold Days. The armour and sword would suggest post Peace Talks, which time it could be several feet.

Toot doesn’t really care about Harry, he cares about the Za Lord, so it is likely Pizza is involved. An attack on Pizza S’Press by a rival fast food chain? Could it be evil clowns?

Hey - toot is growing due to the responsibilities placed on him by Harry - why is Lacuna growing? Heck, she could be a DENT....

Feminist Nuptials - the groom is the one being given away....

I don't think being in contact with your coin is foolproof - Eldest Gruff took out Magog still holding his coin, and his head on, and didn't several drown in the aquarium when Harry blasted the glass? They were not separated from their coins that we know of until they died.

Question on the Wendigo - if you lure it into a circle and activate.... the ectoplasm turns to goop, right? Have we seen evidence a Forest People can possess anything? They have been resistant to magic, but how much have we seen them USE it?  They may be so resistant they cannot manipulate it. Maybe it is a spirit and ALL ectoplasm? If so, Harry goes and sees Forthill, and comes out with the SuperSoaker of Doom.... 1 squirt banishes the ghost and dispels the ectoplasm...
