Debbie asked Sophia Rose:

Do you know how to add an unpublished book onto GR? Sheila and I were exchanging our impressions of The Great Game by Ayden. We both want to do a GR review, but it's not listed in GR, even though 2 of her other unpublished books (Ebb and Flow and The Improvement of Her Mind) are. Looks like someone else, NOT the author, had gotten those onto GR.

Sophia Rose Yes, I've added books before though I'm not sure how it will work with unpublished ones with all the fields they ask to be filled out, but you can try. First, go to the author's page: https://www.goodreads.com/author/show...
In small print under the list of books, there is a statement about adding books and asks you to 'click here'. Click it and it will take you to a page to fill in the known data on the book. For the description (blurb) and other pieces you can probably go to the fan fic site where you found the book. But I think that should do it.
