As I've noted before, I've got a sequel to Back from the Dead called Insidious, which looks at the basic zombie template that's been so popular from a different perspective, sort of merging it with the idea of demonic possession. Hopefully I'll start writing that soon. It'll be followed by Shooks Run, which is another sequel, this time to Leopold's Concentration and Roadkill Cafe (all three of these existing stories are featured in Monorama), completing a story I've been working on since high school, tying up all the loose ends of the mythology.
Now, obviously I've written a number of stories based on Star Trek (as well as other established properties). The third serialized story I'll be working on is based on Firefly/Serenity, and it's called Browncoats. It'll be based on thoughts I had while reading E.L. Doctorow's The March, and in fact parallels one of its subplots.
And whether you like it or not, but the NOVA wrestling story continues as well!
