The Time Quintet is a fantasy/science fiction series of five young adult novels written by Madeleine L'Engle. Publishing history The series originated with A Wrinkle in Time, written from 1959 to 1960 and turned down by 26 publishers before Farrar, Straus and Giroux finally published it in 1962. A Wrinkle in Time won the Newbery Medal and has sold over 6 million copies. The sequel, A Wind in the Door, takes place the following year but was published over a decade later, in 1973. A Swiftly Tilting Planet, set ten years after A Wrinkle in Time, followed in 1978. The fourth title of the quintet, Many Waters, was published in 1986, but takes place several years before A Swiftly Tilting Planet. This is readily apparent from the fact that Sandy and Dennys Murry are in high school as of Many Waters, but refer to their college studies at the time of A Swiftly Tilting Planet; and from Meg's unmarried status as of Many Waters. The final title in the series is An Acceptable Time, published in 1989. All five titles have been published in numerous editions over the years, with occasional changes in cover art and, in 1997, a new introduction by L'Engle for the Dell Laurel-Leaf paperbacks. The books have also been packaged as a box set, first (before the publication of Many Waters) as the Time Trilogy, next as the Time Quartet, and finally in its entirety as the Time Quintet. In May 2007, the books were reissued under the Square Fish imprint in both mass market and trade paperback form. Both editions include new cover art, "An Appreciation by Anna Quindlen", a "Questions for the Author" interview, and the text of Madeleine L'Engle's Newbery Medal acceptance speech, published under the title "The Expanding Universe". Overview This series follows the lives of Meg Murry, her youngest brother Charles Wallace Murry, and their friend Calvin O'Keefe as they try to save the world from evil forces. The remaining Murry siblings, twins Sandy and Dennys Murry, take up the struggle in one volume from which the other protagonists are largely absent. A further book about Polyhymnia O'Keefe, the eldest child of Meg and Calvin, features several characters from the other novels and completes the Time Quintet.
