According to Donaldson:
I have just delivered the third draft of THE LAST DARK. Under the circumstances (the circumstances being that Putnams has already put the book on their schedule for October), I have no doubt that this will constitute D&A. For me, the next step will be copyediting; but of course my publishers have a variety of things that they need to get done.The novel will be published in November 2013, thirty-six years and six months after the publication of the first novel in the series, Lord Foul's Bane.
Just to provide a frame of reference: this draft is 932 pages (not counting WHAT HAS GONE BEFORE and the Glossary). I've done some rather draconian cutting, all of which I believe was necessary. I deliberately wrote the first draft *long* because I wanted to be sure that I didn't leave anything out. But the result was an unusually high number of repetitions and digressions; and weeding them out--while creating more effective or at least more efficient alternatives--has been a very long and arduous challenge.
