I listened to about half of this on audio, it dragged a bit, I switched to the book, it dragged a bit more, and then it got exciting near the end. I know the history of this series' publication, so I had appropriate expectations, I think, but I still expected it to be better-written/edited. I must admit while I anticipated one revelation, I definitely didn't anticipate another one, and I always appreciate that. I won't be continuing though. (I did really like Clockwork Angel, so I'm guessing the writing and editing has improved over time.)
