So I'm part of this shared world project being run by Phil Athans and Mel Odom. It's called The Fathomless Abyss, and is a pretty neat little deal. Lots of details on the world and the publishing concept here at Phil's blog. We've got a pretty cool bunch of contributors, including Philip Athans, J. M. McDermott, Mel Odom, Cat Rambo, Mike Resnick, Brad Torgersen and of course, me. My story in the initial release is "That Which Rises Ever Upward", and deals with grand ambition among people with limited means.
In the spring, we'll be releasing a series of novellas set within the shared world, one by each contributing author. I haven't written mine yet, but inspiration will surely strike.
