Is anything known about a successor? I tried searching for info but with the TV series going on right now I didn't find info on a potential new book.

@tofuwabohu@wyrms.de I haven't heard anything, but Martha Wells has a newsletter you could sign up for on her website, so maybe that's something. Not sure how much she's involved with the TV show, but historically this has been something which tends to delay progress on various series. From a plot standpoint, I think that this would be a nice place to end things, but I also think that there is plenty of space left for further plot & character development. I for one would definitely like to see how the things set up in the end of this one play out.
