Lord of the Flies by William Golding

Over the island the build-up of clouds continued. A steady current of heated air rose all day from the mountain and was thrust to ten thousand feet; revolving masses of gas piled up the static until the air was ready to explode. By early evening the sun had gone and a brassy glare had taken the place of clear daylight. Even the air that pushed in from the sea was hot and held no refreshment. Colors drained from water and trees and pink surfaces of rock, and the white and brown clouds brooded. Nothing prospered but the flies who blackened their lord and made the spilt guts look like a heap of glistening coal. Even when the vessel broke in Simon's nose and the blood gushed out they left him alone, preferring the pig's high flavor.

With the running of the blood Simon's fit passed into the weariness of sleep. He lay in the mat of creepers while the evening advanced and the cannon continued to play. At last he woke and saw dimly the dark earth close by his cheek. Still he did not move but lay there, his face sideways on the earth, his eyes looking dully before him. Then he turned over, drew his feet under him and laid hold of the creepers to pull himself up. When the creepers shook the flies exploded from the guts with a vicious note and clamped back on again. Simon got to his feet. The light was unearthly. The Lord of the Flies hung on his stick like a black ball.
