Emily falls down the New Moon stairs and is threatened by crippledness. She lives nights of pain and despair.

But in the long nights when everything was blotted out by pain she could not face it. Even when there was no pain her nights were often sleepless and very terrible when the wind wailed drearily about the old New Moon eaves or chased flying phantoms of snow over the hills. When she slept she dreamed, and in her dreams she was for ever climbing stairs and could never get to the top of them, lured upward by an odd little whistle–two higher notes and a low one–that ever retreated as she climbed. It was better to lie awake than have that terrible, recurrent dream. Oh, those bitter nights! Once Emily had not thought that the Bible verse declaring that there would be no night in heaven contained an attractive promise. No night? No soft twilight enkindled with stars? No white sacrament of moonlight? No mystery of velvet shadow and darkness? No ever- amazing miracle of dawn? Night was as beautiful as day and heaven would not be perfect without it.

But now in these dreary weeks of pain and dread she shared the hope of the Patmian seer. Night was a dreadful thing.

-Emily’s Quest ch.7

And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
