Book promotion

Hey there socialites. So, I was looking to try and promote my novel, Apocalypsis, (not yet published) on YouTube via a short video. I’ve already created a couple videos for Part 1 and Part 2 of my novelette, Offering. You can watch them at https://www.youtube.com/watch?v=s95b0AtHegw and https://www.youtube.com/watch?v=EsIS8Km-3II. I intend to use the book cover seen below along with some descriptive text to act as an introduction I would create in a short video. My goal is to get people aware and interested in the novel. If they subscribe on the website at jgordonfiction.com, they can view a narrated video version of the Prologue. I’d like to get a larger following. That’s probably the biggest thing holding me back from publishing right now. Any thoughts on this?
