I'm loving Milida's Arabian Nights Gender Changing World. Inspired by an idea from Mr George and Milida, I sketched an outline and happily wrote towards a particular large plot here, having some fun along the way. I took those 1st drafts & polished them. Now, on almost exactly my 10th anniversary here, I've completed the saga. 12 books (about 420k words) in all: https://www.amazon.com/stores/Selkie-TG/author/B075PN4X4T or https://www.smashwords.com/profile/view/elken (I write on other adult TF/TG projects, including some editing for other writers, the game Trap Quest, and mainstream fiction too.
