Speaking of free marketing...
HERE is my just released, first-ever self-publishing venture. Yes, yes, I'm a self-pub virgin no more.
Marlboros & Magic is the short-story prequel to my Persephone Alcmedi series. It first appeared in an anthology, but if you missed it, now's your chance to find out exactly what silly events led to Nana getting booted out of the retirement community (and resulted in her living with Seph).
As for the whole of the topic this week, I dunno. Facebook is my favorite. I poke around twitter sometimes. I've paid for blog tours when I've had a new release. Since I don't track sales, I have no way of know if any of that has an impact, or which is better than another. Other than that, see Jeffe's post from Monday. :)
