Unfortunately, the AI site I was using to revise my book I was writing got blocked because the comments section was used as a chatroom. The book was saved to the local drive, so there's no chance of recovery. I'll have to start over from the beginning of chapter 2, which was last saved about a year ago.
EDIT: I have decided to completely scrap and restart the book. Chapter 1 is in progress. If you want a sneak peek, please contact me.
