It was a dark and stormy night; Meg Murry, her small brother Charles Wallace, and their 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 you don't know) is a wrinkle in time. To tell more would spoil your enjoyment of Madeleine L'Engle's unusual book.
