Everyone likes a bit of variety. I'm sure none of my readers only want to read about anti-heroes or villainous protagonists any more than they only want to read about square-jawed heroes doing the right thing. I just write characters than entertain me and hope they'll be ones that other people want to read about, too.
I have a slightly crap blog where I opine on anything that occurs to me and run the occasional silly competition.
I manage to read about one book a month, all fantasy these days.
When I started the 'Broken Empire' trilogy, I thought it was a short story, and I didn't know the beginning, middle, or end of even that.
