Ambiguous Endings

At the recent production meeting we had a discussion on ambiguous endings. Some editors like everything tied up in a neat little bow. Some editors like readers deciding for themselves how the story ends based on the author's clues. It's actually not the first time the topic has come up. One of our retired editors often lobbied for stories that let the reader decide; she said it was more literary and sophisticated.

So, anyway one of our editors is currently working with one of our authors on a story ending. We'll see what they come up with...

What's your preference for a story ending?
