Audible at least used to have a buy a years worth of audio book credits upfront option that was cheaper then the buy and get a book credit monthly option. If you go that way you could maybe save a bit and grab 12 Dresden books up front.  Then if you let the account sit around for a couple months with no credits in it they will probably offer you a buy extra credits at a discount option.  If you want to get the entire series on audio that is probably the cheapest way to go. 

Unless that is you have all the books as ebooks for kindle.  In that case amazon will usually offer a discount to also get the audio version.  If were starting from scratch and always wanted both that is probably even cheaper but not cheaper if you do not already have or need the kindle version.  I sometimes watch for the $1.99 kindle book deals just so I can get the discount on an audio book as the discount will almost always save more then the $1.99 just not as much a full priced ebook.

The point about Thomas is if he can be mortal, then what's stopping some other wamp from being "mortal enough."

Obviously the shapeshifted mortal doesn't necessarily count. (There is a reason I put a question mark on all these). He might not even have been a mortal in the first place. I know no one has said anything about the Denarians in the books, but my question is why? The mortal half of the Denarian equation is necessary, so he's definitely killing a mortal with magic.

The first law of magic is "thou shall not kill." The implication is "a mortal with magic." The Denarian example proves that one or more of these words is colored with shades of gray. Or he's violating the first law when he kills Denarians.

I would say a killing a Denarian directly with his magic would count as black magic.  I can not remember if Harry has actually done that however.  For example he used wind to push a falling Denarian into the Denarian magic barrier.  The magic barrier killed them not directly Harry's wind magic so that would not be black Magic.   

I love his books, but I've never bought this "lack of writing space" excuse.

Having worked from home the lack of space makes sense to me when combined with the house building as covering a fair amount of lost time.   When I first started working from home I would set up anywhere and it took me a while to realize I was getting almost nothing done. Then I cleaned out a space for a small office and things got a lot better.  If Jim did the same thing we wasted a chunk of time not really thinking about the fact he was getting almost nothing done on the dinning room table.  Then he may have been thinking the new house will be ready soon not worth worry about I will carry on this way.  Then the house kept having delays.   

This does not explain all of the delay but I think the lack of writing space was certainly real and cost him a good chunk of time.

Jim mentioned taking a negative 18 hit to [something] in [some game] to cast the spell. Apparently, from the way Jim said it and audience reaction, that's bad. I didn't catch the something or the game, and I'm not very experienced in RPG's outside of 90's Nintendo games.

I would take that to mean you need to think about it as rolling a 20 sided dice. If you roll a 19 or 20 it works anything else you are at zero or less meaning it does not work.  In other words you have a 1 in 10 chance of pulling off the spell.  Guessing a bit but it may well mean 9 out of 10 times the vampire gets to tear you apart because you are so tired from the failed spell you have no chance and had to be near the vamp to cast it.

  First of all you have to decide whether or not Mab was waiting for mortally wounded Harry to fall into the water so she could immediately put the freeze on him to stop him from completely bleeding out before she could get him where she could care for him.  Before that whether or not she influenced the wind enough to ever so slightly alter the bullet so it would do significant damage but not completely blow Harry's heart apart, but Uriel may have done that part...  In my opinion the answer to both is yes, more over I think it was Uriel who tipped her off that this was going to happen..  Remember Mab didn't get her way here.  If she had, the whole thing wouldn't have happened in the first place, she would have stopped it cold, put some hurt on Harry to put him in his place, but end up with an undamaged Winter Knight.  Recall that she is a bit pissed that Uriel overruled her because it was important for Harry to learn some lessons vital to the cause that they have in common...  However his plan put her future Knight at great risk and she wasn't at all happy with it.

I think she is pissed with Uriel for risking his soul by sending him back not because he stopped her from saving him. it may also slowed down her ability to heal him costing her power.

I also very much doubt she was waiting to save him because I think in that case she would have just stopped the bullet no matter whay Uriel wanted.  I can however totally see Uriel warning her just in time to get there to keep Harry alive but not soon enough for her to have interfered with the shooting itself. 

I find it implausible that Sarissa's "condition" would be something that conventional medicine would recognize as "congenital dementia."
I find it implausible that a changeling daughter of Mab's only coincidentally happens to have a "condition" that lets Mab get what she wants.
I find it implausible that Sarissa is only working with Mab/Winter/mom on a transactional "I do task-X, get paid reward-X" manner.

Have you considered the idea that Mab either faked or gave her the condition just to set things up?  Convincing someone they are sick so you can help them seems like a very winter thing to do.  Plus if by having her under control like this has allowed Mab to more easily keep her safe Mab would see faking the illness as doing the right thing. 

I find it implausible that Sarissa's "condition" would be Nemfection.
I find it implausible that Sarissa would carelessly Leave A Clue like this in front of a professional investigator.
I could go on...  ;-)

I agree with this I do not think it is Nemfection.  If it was that Mab would just cure her. We know she can remove it given time and fighting the outsiders is part of her purpose so she would not take 1/2 measures in that case.

Why would a full wizard of the White Council ever agree to such a menial task?

I would guess the job is on some kind of rotation and that everyone in the rotation gets out of some other duty that no one likes.
