I wrote a short story which is up on Amazon today. In The Device, a person grapples with the effects of an implant which will allow him to shut off all pain at will. While wrestling with his own demons, he lives his life to free others from the machine in their heads.
Since it is a short (3,500 words), the social commentary is a little more pointed than in my other two published pieces of fiction, but I think I managed to avoid sounding preachy.
I like this one. It is dedicated to everyone who is willing to face their pain and discover its creative purpose. I think that is all of us in the end.
