Proven Guilty - Jim Butcher

Proven Guilty is the 8th Dresden Files novel.  This time Harry is fighting some nasty phobophages at a horror film convention.  You'll never ever guess who lured them to our world.  Harry and the usual group of friends have to fight their way into the nevernever on a mission to rescue the guilty party.  Meanwhile, Harry is involved in the political intrigue of the white council and fighting for his life once again.  Highly recommended.
