Hello Terence,
We can work together to market your book. It looks like you already have the basics set in stone. You have a website, inactive social media accounts, and really good reviews.
Some suggestions we can work on after learning about what has been done in the past is running ads, creating a blog, activating social media and a few other to work on.
If you're interested, please chat with me as I think this would be one of the most interesting projects I applied to for a while.
