#3: The Hedge Knight and The Sworn Sword by George R. R. Martin
These two short stories together make a neat little novella regarding a couple adventures of Ser Duncan the Tall, a hedge knight of little repute. He gets caught up in - and often provokes - situations far above his usual station, simultaneously evoking sentiments of the "for want of a nail" variety and reminding readers that the vast majority of the people of Westeros have very little input in the course of their own lives, compared even to hedge knights, to say nothing of lords and princes.
All together it's an entertaining couple of stories, and I hope we see more of Ser Duncan (though not before A Dance with Dragons is done, please). The story makes for an excellent introduction to Westeros, containing only very minor spoilers for certain minor characters' backstories in the main series. (I also just saw an offhand reference to something from the short stories in A Feast for Crows, so that was a nice bonus for reading it first. Thanks, Sheree!)
Obviously, A Feast for Crows is up next. And then I'm out of books in the series for now. Sigh.
