Well, he was working on a novel for a while (I guess in between all his other projects) which was going to have a "mainstream" theme.
Here is his posts about it:
I should be able to announce one other project, the last I could take on at this point, in about a month or so. The contracts only now got signed. And I'm now about halfway through the new novel I'm writing, which should be going out to auction in January (assuming work allows me to finish it by then).
"Mr.Straczysnki, I am currently reading your novel "Othersyde". It is a wonderful novel, are you going to write anymore in the near future? I will try to read the other ones, if I can find them."
The drag is that I was a couple hundred pages into a new novel, mainstream, when the events of 9/11 happened and I had to spike the novel because everything that happened since that day (with a few minor variations) lined up pretty much with my book, which kills any chance of publishing it.
Takes a while to come back from looking at two-hundred-plus dead pages.
On a happier note, I'm in the process of signing a deal that will put all three of my novels, plus my anthology, back into print early next year.
