1. We have been told that Nicodemus has a very specific target in mind, ostensibly kept in the Labyrinth of Daedalus.  What is Nic trying to get his hands on and why?

My bet is one some article of power to use in the BAT. Nic is usually all about chasing the apocalypse but I think he sees things are becoming dire he might need a power up.

2. Nicodemus apparently called in a marker from Mab to get Harry on the team.  Does he have a specific plan for using Harry or did Mab twist his request?  Which of Harry's capabilities will he admit to needing, and (given that this is Nicodemus after all), which abilities is he scheming for Harry to use?

I think Harry having died and come back will show some of it's significance in this book. Hades will probably be interested in such a person.

3. Jim has mentioned that the book will be "Ocean's Eleven".  Who else did Nicodemus recruit?  How will they interact with Harry?

I'd rather see a mixed bunch than his typical Nicklehead crew. The churchmouse will probably be there, and I think a naagloshi is heavily favored in the general opinion because of the name of the book.

4. Harry's general method of operation is to call on his friends for help.  In this book, Harry is (initially) allowed one extra backup member on the crew.  Who will it be?  Which of Harry's other allies will "interfere" before the plot is over?

I was trying to think which of his usual companions he hasn't had a book with lately. Thomas was featured heavily in the CD, as was Molly and she's probably on the shelf for this one at least until its climactic to reveal her winter lady goodness. Mouse isn't a bad idea but I don't really consider him a Major companion if that makes sense. Murphy hasn't been used for an entire book since, what Changes? And just having a sword with her, even if she doesn't take it up, could be a good threat to keep Nic in check.

5. This is a Denarian book, so (unlike the last "end of the world" showdown), the Swords will almost certainly be present.  In fact, there have been various hints...  Which Sword wielders will appear in the next book and how will their interference/help affect the plot?

My dream scenario is that when all looks lost for Harry that Sanya, Murphy, and Daniel Carpenter run in and rain holy death on some fallen/demons with all three swords.

6. Mab is apparently against Nicodemus succeeding in this heist.  In the Cold Days, we found that Mab had complex reasons for wanting Harry to kill Maeve.  What are Mab's reasons in this book?  Is it simple thwarting or is there something deeper?

I believe she mentions in the reading that Harry is there to make sure whatever Nic is planning doesnt go down. Couldn't really guess as to what or how or why at this point.

7. At the end of Cold Days, Harry needs to stay on the island to keep his growing headaches at bay.  The start of Skin Games implies that those headaches will need to be resolved by the end of the book.  Who or what is causing those headaches, and how will the whole thing get resolved by the end of the book?

I believe it's Lash, corrupted by Nemesis (somehow) and Harry will rid himself of it when he finally takes up her coin provided by Nic at the best possible moment. Hell Harry already has the mantle to deal with, some serious anger issues, and a world of guilt on his shoulders. I don't know if you guys watch Breaking Bad but he's getting to be more Heisenberg and Walter White at this point. One more nasty influence in his head doesn't sound like an illogical next step.

8.  One of the key components of the "Ocean's Eleven" movie is that there is a final twist/reveal.  Given that we've got Nicodemus, Harry, Mab, and potentially Hades (and who knows who else) all trying to get the better of each other, if there's one thing you can count on it's some sort of last minute quintuple-cross.  What will be the nature of the twist and how will it all fall out?

Nic and Hades were working together to deliver Harry to the underworld where Hades believes he belongs. Of course Nic double crosses Hades and takes what he wants from the vault as well as his original payment. Hades then makes a quick deal with Mab aaaand fireworks.
9.  (Extra Credit) There are many WAG ("Wild A$$ Guess") theories on the boards, some crazier than others.  Write up to three WAG theories (or make up your own) you believe are correct that will be confirmed (or at least have evidence in favor of) in Skin Games.

1. Eb is infected as well as the leader of the Black Council.
2. Justin was working toward the same goals as Maggie and sent HHWB to give Harry his first piece of knowledge about outsider/being a starborn.
3. Kincaid was a denarian at some point.

10. (Extra Credit) This is that "free form" question where you can come up with anything else you think will be in this book.  Specific quotes Harry might say (will he actually quote Ocean's Eleven?  The movie will have come out already in Harry's timeline)? Tidbits about the White Council? The fate of Molly? Write down anything you want.  Note that whatever you write must be specifically mentioned or hinted at in Skin Games in order to be worth credit.

I got nothing.
