Just to answer a question I’ve been seeing frequently and to provide some reassurance once I’ve answered it:
YES, Shadow Scale is the conclusion to Seraphina’s story. Everything wraps up, perhaps not entirely tidily, but in satisfactory and life-like fashion.
HOWEVER, let this not be a source of sadness for you. Goredd won’t just disappear. Indeed, those who have been with me since my comic book days, before Seraphina, know that Goredd and I have been together a very long time. It’s an enormous world, I love it, and I am going to set more books there. I am already working on the next one (I’m about 85K words into it, in fact).
The world came first, and the world goes on.
