Free downloads up 65%! (+ NEW BOOK?)

Free downloads of my Smashwords books have gone up 65% since last month! That is a marked increase, almost getting to the 500 per month point, which would be nice!

Free downloads of "Rage" didn't go so well, but well over 1000 people (mostly for free) have that already, so I guess I've hit my 'small fish pond exposure ceiling' with that one.

I'm finally having a look at my little sci-fi book "Gubacsi Dulu" which I started a few years ago but never finished. I wonder how a sci-fi would go in my 'small fish pond'?
