I'm on the last 100 pages of my western ("Lavender Lady") and sort of floundering around through the last steps of the "W" diagram (crisis, resolution, etc.)
I just received my San Francisco RWA chapter newsletter and in it there is an article (by Shelley Bates) about Alicia Rasley's wise words on how to end books.

Rasley is straightforward and specific: "End a scene after something happens, either a disaster or a surprise." And "Keep the emphasis on doing, not enduring bad things happening. Come up with four or five events and assemble them in an order that keeps up the pacing--easiest to hardest, least dangerous to most dangerous, leaast to most emotional risk or pain." [italics added--this is what is helping me through the muddle]
