Oh good grief, I just had a new novel install itself in my brain and shriek WRITE ME NOW (spoiler: I can't do that, there's a queue).
Working title: "The Stainless Steel Rat gets Isekai'd".
(NB: it'd be an in-universe followup (not sequel) to "Ghost Engine", but GE needs a redraft and publication first!)
@cstross I had a story do that to me on Friday. Unfortunately I was still working and the best I could do was write up the idea in One Note and then not get around to writing all weekend. :(
@Sharan This is definitely novel length. And not a short novel, either! (The way plans for the third draft are going, Ghost Engine is heading for 200K words, and this hypothetical follow-up is looking like 120-180K words.)
