Sounds mutually beneficial, I LIKE IT!.

Also, illustrating my fiction is exactly why I got into AI art in the first place. I am happy to help you learn how to use StableDiffusion and all of its associated models, happy to instruct you to just use Bing to make images in Dall-E3 instead, and happy to make them for you if you'd prefer. (Dall-E3 is easy, free, and impressively accurate, but I think I tend to bring a style with StableDiffusion that mostly cannot be found elsewhere)

I'd also advise you to download Obsidian onto your PC/laptop. I've used Google Docs for most of my writing, but it became overwhelming to try to organize it all. Then I bought a license for Scrivener, but it seems a bit daunting to learn how to use properly (and seems like something I will end up using to finalize my book). Then I found Obsidian, which is totally free, and got as much done with that in a day as I did with Scrivener in a month. It's just super-useful for organizing. 😉👍
