Found: Three scrapped pages from A Wrinkle in Time.
From the WSJ:
Madeleine L’Engle, the author of “A Wrinkle in Time,” resisted labels. Her books weren’t for children, she said. They were for people. Devoted to religious study, she bristled when called a Christian writer. And though some of her books had political themes, she wasn’t known to write overtly about politics. That is, until her granddaughter, Charlotte Jones Voiklis, came across an unknown three-page passage that was cut before publication.
It reads rough and didactic for sure—and for those reasons I'm glad it was ultimately cut from the book—but I'm so glad to have gotten the opportunity to read it. They've posted the entire three pages, so click on through while you can—I don't know how long it'll be up!
