Her death, of natural causes in a nursing home, was announced September 7 by her publisher, Farrar, Straus and Giroux, according to the Associated Press.
L'Engle was best known for her children's classic, "A Wrinkle in Time," which won the John Newbery Award as the best children's book of 1963. By 2004, it had sold more than 6 million copies, was in its 67th printing and was still selling 15,000 copies a year, the New York Times reported.
She had been the writer-in-residence and librarian at the Episcopal Cathedral of St. John the Divine in New York City.
In her own words:
“Why does anybody tell a story?” she once asked...
“It does indeed have something to do with faith,” she said, “faith that the universe has meaning, that our little human lives are not irrelevant, that what we choose or say or do matters, matters cosmically.”
