Summer Knight is my favorite of the Dresden Files books thus far. Harry gets entwined with a Faerie war. These aren't sweet Tinkerbell type faeries either, but the stuff of old tales: treacherous and deadly faeries that are more likely to harm a person than help them. The faeries in this book reminded of those in Susanna Clarke's Jonathan Strange and Mr.Norrell, which is a good thing. I think that this book is a little less formulaic than the previous books are. It delves more deeply into The Never-Never and the creatures within, which shows off Butcher's creativity and the world's mythology. I also like the nods to Shakespeare and nerd culture. Harry Dresden always gets himself into impossible situations and I love to see how he manages to get out of them and save the day.
