Find a new author. Accept that this universe is dead. If he had something worthwhile to write for the Dresden Files, this book would've come out two years ago. Clearly, he's stuck, the cavalcade of excuses notwithstanding. Appreciate what was written to this point, and acknowledge that the rest of the story ain't getting written or published. Not a bad reminder to us all - don't become emotionally invested in any author's long series - there will be a sharp dropoff in quality, quantity, or both.
