Bitter What?

I think I'm going to put this on my list of typos and mistakes I hope to avoid. Or at least catch before I send my MS off to an editor or agent. From this review by Jane Morgan: "The ending was bitter sweat and left me wanting to read the next book, and soon." Now, the brain can do all sorts of funny things when you're writing fast and focusing on something else. But this is exactly the kind of thing you really hope you catch during edits.
