|Meadows's fix for saggy middles: Blow it up!|
I'm not sure how much you can tell from single lines, but it would be cool if one's first, exact middle (check your page count, divide in half, put finger on midpoint), and last line could tell the whole story of a novel. Here's the trio from Hitchhikers Guide to the Galaxy:
Middle: "Trillian," he said, "is this sort of thing going to happen every time we use the Improbability Drive?"
Last: "Okay, baby, hold tight," said Zaphod. "We'll take in a quick bite at the Restaurant at the End of the Universe."
Sweet! And by the way, I'm LMAO reading this Douglas Adams classic. Pick it up if you need a lift.
And here's a famous kidlit first line quiz that's kind of fun, as long as we're vaguely on the subject.
