The Short Sale book cover


Since 2012, I have wanted to write a novel. I had envisioned the opening scene many times. I wanted a hacker targeting his prey at a coffee shop. This victim regularly used the coffee shop’s free WiFi. The hacker had already broken into the WiFi and was looking for data to use for an attack.

In 2015, I watched the previews at the movie theater while waiting for the “Avengers: Age of Ultron” movie to start playing. I saw the preview for the “Mr. Robot” show. I pointed at the screen and said, “That’s kinda like my book idea!”

A few years later, I saw Mr. Robot on Amazon Prime Video. I was shocked at the opening scene. I could not believe it. The hacker was at a coffee shop targeting his victim! As the Mr. Robot story unfolded, the plot’s direction differed from what I wanted to do.

I have been debating for a long time whether to pursue this book idea. I decided to release the book serially on Medium and gauge interest. I could continue releasing chapters with interest from the audience. If there is no interest, at least I took action on my book idea.
