I have, however, continued to make progress. I'm now working on chapter 10 of Perilous Waif, and I think I've finally got the majority of the worldbuilding I need to support the story finished. This setting is definitely too big to explore in a single series, so I may end up using it for other SF stories in the future.
The first two chapters of Revenant have undergone a major rewrite, as I got a much better idea for how to handle some critical plot points. I'm now working on chapter 3, and I expect I'll start putting out chapters a little faster from this point on.
In other news, the audiobook version of Fimbulwinter is now on sale. The Black Coven audiobook is currently in production, with Extermination to follow. I'll post an announcement here when they become available.
