The Dreaded Synopsis

You've wrote a story...now what...?  You get to write a synopsis for that story.  Easy, you say?  Not so much, say I.

I've been sitting here trying my best to come up with a small synopsis of my little ghost story and I'm finding this harder than the actual writing of the story, itself. 

Sure I know all the small plot points and character developments I've placed throughout the story but how do you give a small cliff-notes version of that without saying too much?

It's different with a novel, I'm supposing, since you can basically explain the opening chapter and then you can leave the rest of the book to do the majority of the talking for you.  With a short story, though, you can't do that.  I've got 60 pages, depending on your font size, that I need to condense into a small blurb.  A blurb that will decide if people hit the 'buy now' button on their ereader or browser.  Just a little bit of pressure.

Any ideas, out there, on the best way to go about this?
