A really cool children's fantasy/sci-fi book written by Madeleine L'Engle, published in 1962. It tells the relatively short yet fascinating story of a New England teenage girl who goes on a journey with her brother and friend/boyfriend to save her father. It is a tale of science, love, mystery, good and evil, and portrays a great message of individuality and creativity. It won a Newbery Medal and for good reason, it's awesome!
It is the first in a series of something like 6 or 7 books, all which are good but not as good as the first one.
"You're given the form, but you have to write the sonnet yourself. What you say is completely up to you."
- Madeleine L'Engle, A Wrinkle in Time
