It was a dark and stormy night; Meg Murry, her small brother Charles
Wallace, and her mother had come down to the kitchen for a midnight
snack when they were upset by the arrival of a most disturbing stranger.
"Wild nights are my glory, " the unearthly stranger told them. "I just
got caught in a downdraft and blown off course. Let me sit down for a
moment, and then I'll be on my way. Speaking of way, by the way, there
is such a thing as a tesseract."
A tesseract (in case the reader doesn't know) is a wrinkle in time. To
tell more would rob the reader of the enjoyment of Miss L'Engle's
unusual book.
