Sorry, I thought you were referring to book 3. Book 3 is still in progress on Patreon. It'll be completed on Patreon soon and chapters will be posted on here starting next week I believe.
I guess if you go by the lowest tier, you have not finished book 3.... but at the same time lowest tier mentions that its ahead only 15 chapters not "one book and 15 chapters", 78 chapters in this case...
The lowest tier of my Patreon is 15 chapters ahead of my Royal Road release schedule. I decided not to post on SH until each book is complete simply because it's easier for me.
This is my first story posted to Scribble hub, but certainly not the first one I have written. Check out the link below for the rest. Also thanks for reading my story, I really appreciate it and I hope you are enjoying it as much as I enjoy writing it.
