Neptune's Brood is due on bookshelves in just over two weeks' time. (And some of you lucky people will probably be able to get your hands on paper copies of it a bit earlier.)
It's set in the same universe as Saturn's Children, but a whole lot later. That one was originally written as a stand-alone novel, so why am I going back to the setting?
Well, "Saturn's Children" was indeed a stand-alone when I wrote it, but over the next couple of years I didn't notice any huge holes in the world-building. I had no plans to re-visit it, mind you, but unlike the Eschaton series there was no reason why I couldn't go back there in principle.
Then Jonathan Strahan got in touch. Jonathan is a talented editor, and among the things he edits is a series of theme anthologies. In this case, he wanted to commission a story for an anthology titled Engineering Infinity. "I want hard SF stories, for a new century," he said (I'm going from memory here). Which gave me a headache thinking about it, but then I realized I had a loose end left over from "Saturn's Children", and read a write-up of a funky new phenomenon in high-energy astrophysics in "New Scientist", and suddenly ... bingo! I had "Bit Rot". And more importantly, I had the realization that there was room for another novel in this universe—because if I could write a short story, I could tackle a more ambitious project.
So, without further ado, here's the missing link between "Saturn's Children" and "Neptune's Brood":
