I was right when I decided that Dust is a big book chunked up into thirds.
I can tell, because I just hit The Dreaded Middle Of The Book.
On page 295 of Pinion. As I am being faced by a bad moment of "but wait, this makes no sense!" combined with a certain amount of "So how do I tie up most of these plot threads while leaving enough of a hook behind for the next book to railcar into?"
Yeah, Sanction is going to be fun.
(Just keep throwing cool stuff at the page and maybe nobody will notice that you have no freaking idea what you are doing. Also, remember that your subconscious is much better at all this than your front brain, and it knows how the story should go, and if you give it a chance it will find ways to tell you.)
and I'm gone like I'm dancing on angels
