I'm using my short story, Right Now, to try my luck with the KDP select program. For people signed up foe Amazon Prime it is free to download.
For those of us who haven't signed up for Amazon Prime, its only $0.99.
Now, of course, with KDP Select every 90 days you can slate 5 days where the writing is free to everyone. So you can get my book free here: http://www.amazon.com/Right-Now-ebook... on March 5, 7, 9, 10, and 17(just had to do that, March 17 is my Birthday :P)
