Fold Space 2 - five chapters, and over 20,000 words - is now with my editors and hopefully will be ready to post in a couple of weeks. I hope it pleases, if not satisfying, the many readers who have asked for more in that universe. As I was writing, though, I was aware that I was setting up a situation which will demand further episodes. They will not be forthcoming any time soon, I'm afraid.
Just now, I'm making a start on the sequel to 'Zoe' that I've had in mind since completing 'Pippa'.
Just in passing, I'll comment that your encouraging emails really do give me an incentive to write, so I would encourage you always to drop a line to authors, if only to say 'I liked it'.
