Let's talk about your synopsis

I know that a synopsis can be a pain in the you know what to write, really, I do. I know I don't base my opinion of a manuscript on the writing in the synopsis. That's just not fair because some people may really stink at writing a synopsis but their book might be the greatest thing since sliced bread. But, when you write a synopsis, you HAVE to give us all the main plot points. Including the ending. We're an editor, not a "regular" reader. There's nothing that drives me nuts rather than to get a synopsis and not have the ending. It's like needing oxygen to breathe, I need the ending to the book. =)
