Collaboratorium

Been working on a piece of collaborative fiction recently, which is something new for me. We started talking about it two years ago, but as is so often the case, life got in the way and we didn't get traction on the story until early last year. Then ... well, life got in the way again, as it tends to do. After Christmas, though, we decided to return to the story and see if we could finish it.

Right now I think it's about 15,000 words and I think I'm about finished with my side of the writing - there's a beginning, middle and end but still a few rough edges. It's a very far future piece, set on Earth, with a kind of Jack Vance/Gene Wolfe vibe to it. Once my colleague has finished with their side, we'll need to fix a title onto the thing and then we're done. As to where it'll appear, that's already "sorted", so to speak, but it's not going to be a publication that will be easily obtainable unless you are or were signed up for a particular convention. Given the limited distribution, though, I think we'll try and get it out to a wider readership at some point.

Anyone care to take a guess at the other writer in the collaboration? First correct answer will bag a copy of the story, once it's available, and I'll endeavour to get it signed by both of us.

[Edit - strictly one guess per respondent, people (although I'll not penalise those who've already commented). And I'll give it a couple of days before announcing the "winner"]
