Margaret Mahy said this quote

Somewhere int he flesh of the earth the dreadful earthquake shuddered, the tide walked to and fro on the leash of the moon, rainbows formed, winds swept the sky like giant brooms piling up clouds before them, clouds which writhed into different shapes, melted into rain or darkened, bruised themselves against an unseen antagonist and went on their way, laced with forking rivers of lightning, complete with white electric tributaries. Out of this infinite vision an infinity of details could be drawn, but Sonny had settled on one, and from the endless series a particular beach was chosen and began to form around Laura - a beach of iron-dark sand and shells like frail stars, and a wonderful wide sea that stretched, neither green nor blue, but inked by the approach of night into violet and black, wrinkling with its own salty puzzles, right out to a distant, pure horizon.
