No spoilers here because I don't want to ruin it for anyone who hasn't read/finished it yet, but I just want to say I loved this book.
After the heavy stuff of the previous three books, Skin Game was lighter in tone and full of the crazy monsters, humour and movie references we've come to expect from Jim Butcher.
My only gripe is that a couple of my favourite characters were missing, but with so many to choose from, it stands to reason that not everyone is going to get 'screen time' in every book.
Oh, and I would so go for a beer or two with Hades. I bet he's got some great tales to tell.
