You'll probably come to find that this route will be a mistake. The book world is vast and I think your story will be lost in it. AVNs are a much smaller arena and good AVNs are supported. But it's your story, so you'll just have to live with the consequences.
Of course it’s a mistake.
Sadly, those with a vision of how they want to accomplish something are usually blind to any drawbacks, and march willingly down the road to obscurity.
Seen it before. This has all the hallmarks.
Failure to listen to your audience is failure to survive.
Just once, I want someone to realise “Shit, this ain’t gonna work” and return to what everyone’s telling them is the right path.
