Discworld – Lords And Ladies (Terry Pratchett)

The wind slackened. Now it was a whisper around the horizons, as the sun rose.

This was the octarine grass country. Good growing country, especially for corn.

And here was a field of it, waving gently between the hedges. Not a big field. Not a remarkable one, really It was just a field with corn in it, except of course during the winter, when there were just pigeons and crows in it.

The wind dropped.

The corn still waved. They weren't the normal swells of the wind. They spread out from the centre of the field like ripples from a dropped stone.

The air sizzled and was filled with an angry buzzing.

Then, in the centre of the field, rustling as it bent, the young corn lay down.

In a circle.

And in the sky the bees swarmed and teemed, buzzing angrily.
