It must imply tension. And it will have to be the tightest sentence you've ever written. No vagueness allowed. Every word, every word , has to carry plenty of promise. Find a keyword and play with it.

Look for opportunities for wordplay, such as puns and alliteration. These are probably best confined to lighter books, but can add bounce to the sentence.
