I've been plugging away on the book, slowly but surely. Part Two went longer than I wanted. (Big surprise.) I finished it last week, though, and the full book current wordcount is at 247k. (400k is the goal. Note that of that 247, some 20k or so is for Parts Three and Four, as I wrote the flashback sequences for Dalinar all straight through.)
I wanted to be further by the arrival of July, but was slowed down by two things. First, touring in February and March. Writing while on tour is killer, and I tend to be very slow during high-travel times. After that, I spent most of May writing Edgedancer, the Stormlight novella that is going in the Cosmere Collection this fall. (I consider it an apology for not having Stormlight Three out this year.)
Everything is still looking good for an Oathbringer release next year. I don't have any major touring until I go to Europe in October/November, and there are no other projects like Edgedancer on my plate. So at my current rate of 10k a week, without any interruptions planned, I should be finishing up right around the middle of October.
Part Two turned out well, though it's a slower, more lore-and-character focused section. (It includes some viewpoint chapters I think you'll find unexpected and interesting, though it has less action than other sections of Stormlight.)
If you look at the visual outline from the second update, I've finished everything for Part Two. My next task is to do a quick revision of Edgedancer to be turned in this week, and then do a revision of Part Two. I'm doing an unusual thing (for me) in revising each part after I finish it, then sending it to my team for continuity and editing. We discovered that a big slow-down in getting Word of Radiance ready was me waiting for the team to get back with increasingly-complex and detailed continuity notations.
This means when I finish the first draft of this book, it will actually be the second draft, which will speed up revisions a ton. (I should be able to move right into them, and do the third draft right away.)
The biggest challenge for the book will be making sure I don't go TOO long, as (like other Stormlight books) it's important to me that the book be read as a single volume, instead of as separate books published in a split-up way. (I can't prevent this in some markets, though.)
As always, thanks for reading.
