Good job on the finished screenplay, and it sounds as if you're coming along nicely with The Orphan Queen, that's great! And maybe you'll need another 200k words to wrap everything up, which will be okay. You can always publish it in installments. I remember The Glass Books Of The Dream Eaters by Gordon Dahlquist; it was published (at least in Europe) in one go, but it was a number of smaller books in a box set rather than one big Infinite Jest type of novel. I liked that idea.
