I decided to try publishing my science-fiction mystery story, The Singer File, in the Kindle Vella system, which allows me to publish an "episode" (meaning a chapter in this case) at a time and to interact with readers. The plot of the story goes:
The year is 2049, and microchips have been implanted in every human being on Earth. When Global Intelligence Agent Alex Rose finds Doctor Joshua Singer unconscious with his hand cut off, Rose suspects that the violent act may be part of a something much bigger. As forces gather to stop Rose's investigation, he finds himself uncovering dark secrets about the chips, about the world, and about himself. What, if anything, will be left after he reaches the truth?
The first three episodes will be entirely FREE. If it sounds interesting to you, then check out the first episode at https://www.amazon.com/kindle-vella/story/B0B86L89PM
