Thank you for sharing this! I am super excited about ILLUMINATION Book Chapters for this very reason; it is an excellent way to find a new audience for existing published works.
We are working to find new ways to integrate the various ways of self-promotion with the chapters, the books, and the authors here. I have been including links to Amazon and Goodreads where I can in our "Authors Published Here" list for exactly this reason: if a reader likes something, they will want more of it and click that link to see what else you have written commercially.
May you find new readers, and may readers enjoy what they find. I know I do!
