Monday, 9/15, through Wednesday, 9/17, this book will be free. I haven't been able to sell many. Let's see if I can give a few away. It's one of my favorite titles among those I wrote and only one of two science fiction stories.
If it's not posted free right away when you go there, try again. Sometimes it takes Amazon a few hours to get things rolling.
If you like it, post a review. If not, well, post one anyway.
