What's Next?

While we’re waiting on Death by Cliche, I thought I muse a bit on what’s next.  I know I’ve charmed all of you with my comedy, but I haven’t actually written much comedy.  I was thinking about taking the Echoes of Heaven short stories, starting with Ulcer, and serializing them.  They tell a complete story, one that problaby barely qualifies for a novel’s word count (certainly novella).  If you like them, I might start the Echoes of Heaven novel.  It’s serious as well and I think it’s one of the best things I’ve done (it would be hard to judge it compared to my book that’s sitting on an editor’s desk at Tor right now, of course).
So how do you feel about some serious fiction next?
