It was a tweet I could have written myself:
The first half of this book keep growing in revisions, while the second half keeps… not…being revised.
Cut it in half and call it a duology? 😅

(At least the first part of the tweet; it’s pretty hard to create a duology out of a story that’s already been envisioned as a trilogy!)
