What is the setting of Blood Rites by Jim Butcher?

The story takes place in a modern day setting in Chicago. The only difference between the world of Harry Dresden and reality is the existence of magic and the elements that might go along with magic, such as wizards, vampires, magical curses and so on. Harry is the only wizard advertised in the yellow pages. While there are those in the magical world that seem to take Harry very seriously, it is clear that the average person on the streets does not believe in magic and finds Harry to be somewhat of a joke.
