Small Favor, by Jim Butcher

I have a feeling the Dresden Files are best read sequentially. Small Favor (book 10) is so full of threads from previous books, it is a testament to Butcher's skill that it is readable as a stand-alone at all.  A few things are specific to this book, the kidnapping of a gangster and of the Archive, and an attack on Dresden by the Billy Goats Gruff.  A few seeds are planted for follow-up in the next books, like Michael's condition and Harry's emerging precognitive gifts.  Harry's smart mouth continues to amuse.
