I've been getting a few messages asking what's happening since I thought it was going so well a year ago. Two things conspired to sidetrack it.
First, time: it went away. I started a new job shortly after my last update and I've been very involved with it, which has combined with some home life issues to seriously limit the time I can spend on my writing. It's worse than that, though, as I've never been able to keep the flow of my writing unless I'm doing it in sizable chunks.
Second, inspiration: I'm not sure I like where I had the story going. It was starting to feel too pat and condensed but I haven't come up with a way to draw it out effectively. OTOH it may just be my memory of it so I'm going to go back and reread what I have written and see if I like it any better now.
