New ending or leave well enough alone?

I'd planned to finish the rewrite of "Eden's Return" by September 1. Instead, I'll be lucky to get it done by December 1.

I'm not sure why I stalled out.

I managed 10 pages yesterday, which means I have 30 pages to go (in a 200 page book.) I've been tempted to send it on to my editor as is, but have fought the inclination. Re-writing always improves the book.

Yesterday, it occurred to me that I could write a twist ending that might be more satisfying to the reader. I even thought of one. But like all twist endings, it's been done before in one form or another. I mean, it's more than serviceable.

The current ending is soft--on purpose. The whole story is meant as a philosophical mood piece, within a harsh survival story. The soft ending matches the story.

I'll probably stick the ending I have rather than compromise. But I'll probably always also wonder if it was the right decision.
