A Wrinkle in Time
"It's the Thing!" Charles Wallace cried. "It's the Dark Thing we saw from the mountain peak on Uriel when we were riding on Mrs. Whatsit's back!"
"Did it just come?" Meg asked in agony, unable to take her eyes from the sickness of the shadow which darkened the beauty of the earth. "Did it just come while we've been gone?"
Mrs. Which's voice seemed very tired. "Ttell herr," she said to Mrs. Whatsit.
Mrs. Whatsit sighed. "No, Meg. It hasn't just come. It has been there for a great many years. That is why your planet is such a troubled one." (5.100-103)
"But what is it?" Calvin demanded. "We know that it's evil, but what is it?"
"Yyouu hhave ssaidd itt!" Mrs. Which's voice rang out. "Itt iss Eevill. Itt iss thee Ppowers of Ddarrkknesss!" (5.108-109)
Suddenly there was a great burst of light through the Darkness. The light spread out and where it touched the Darkness the Darkness disappeared. The light spread until the patch of Dark Thing had vanished, and there was only a gentle shining, and through the shining came the stars, clear and pure. Then, slowly, the shining dwindled until it, too, was gone, and there was nothing but stars and starlight. No shadows. No fear. Only the stars and the clear darkness of space, quite different from the fearful darkness of the Thing. (6.4)
