How do you write a sequel first?
So, it makes a lot of sense to me. ...I'd written about a quarter of the next Mistborn novel while I was doing revisions for A Memory of Light. I'd send off A Memory of Light, I'd have, like, a month until Harriet got back, so I wrote a little bit of this. It'd come back, I'd stop, I would do the revision, and then I'd go back and have about a month so I'd work on this. The problem is, picking up a book mid-stride, that I had worked on years ago, because then I put it aside and I wrote other things, I wrote Words of Radiance. Coming back to it was really hard. You can imagine that starting mid-stride something that was half-done, might actually be harder than starting something new. When I finished Alloy of Law originally, I plotted a trilogy of books to follow it. Alloy of Law was more freeform; the trilogy, I did my normal build-a-trilogy. So, I had the second book all outlined, I could jump into this a lot easier, there's a break between books two and three, so the characters have reset a little bit, not gone backward, but, you know. Anyway, it was so much easier to go write that book, to get myself back in the world and the mood, then jump back and finish the book before. So that's why you're getting two Mistborn books, rather than one in the next few months.
Which was really fun, by the way, to send to my editor and my publisher and my agent. None of them knew. I sent them an email, I'm like, "Great! The book's done!" And attached were two books. *laughter* And then I went to bed, because I was doing this at, like, 5:00 AM. So, I went to bed, and I got up to a flurry of emails. "Um, Brandon? Do you know? What'd you just do? Where'd that other book come from?"
