I put up the first chapter of my novel-in-progress. It's available at http://fugitiveplanet.blogspot.com (Update: link removed, site taken down). See this post for details on what this craziness is all about.
Note that at this point, I have no idea how the story will turn out, or whether I will even be able to finish the 25,000-word requirement. I have the framework of a story in mind, and I think I can make the concept work. Whether it actually will is anybody's guess.
Update: I've decided not to pursue this. Some other things came up and I will not be able to participate.
