Madeleine L'Engle's "Time Quintet" has long been a staple of young adult literature. The earthy nature of her characters makes you want to follow them on their travels around the quaint Murry farm and, indeed, around the universe. "A Wrinkle in Time" is the cornerstone of the quintet. In it, we meet the Murry's quirky and original family and soon are wishing it was our own--as Calvin does. The scientific idea of the book involves tessering, or wrinkling, time. The more imaginitive setting is the war against "the darkness" seeking to envelop planets. "A Wind in the Door" is a little more difficult as it explores the differences or implications of "being" versus "non-being and the satanic Ecthroi and their war on the universe at ALL levels--even as tiny (size doesn't matter) as a farandola. "A Swiftly Tilting Planet" is a beautiful picture of what can happen when we charge the universe and place ourselves in the gap at times of great need. In ASTP, we find out more about the O'Keefe side of the family and the inhabitants around the star-watching rock many, many years before the Murrys come onto the scene. "Many Waters" is also a beautifully layered book looking at the pre-flood era of Noah and his family. Finally, we get to know more about Sandy and Dennys! They prove to be more that "just kids" as they begin to fit right in, help Noah with his Ark project, and gain the love of Noah's generation. Many great "what-if's" here. Lastly, we have "An Acceptable Time" which follows Polly O'Keefe (Meg and Calvin's firstborn) as she travels through time to the People of the Wind that lived around the Murry's land 3,000 years before they did. Through all her travails, she discovers that her gift and many other things must wait for "An Acceptable Time."
