Book blurb. I like the word 'blurb'.
From Terry Pratchett's Lords and Ladies:
"...what we have here is not a nice girl, as generally understood. For one thing, she's not beautiful. There's a certain set to the jaw and arch to the nose that might, with a following wind and in the right light, be called handsome by a good-natured liar. Also, there's a certain glint in her eye generally possessed by those people who have found that they are more intelligent than most people around them but who haven't yet learned that one of the most intelligent things they can do is prevent said people ever finding this out. Along with the nose, this gives her a piercing expression which is extrememly disconcerting. It's not a face you can talk to. Open your mouth and you're suddenly the focus of a penetrating stare which declares: what you're about to say had better be interesting."
