Time Quintet

The series originated with A Wrinkle in Time, written in 1959 to 1960 and turned down by 26 publishers before Farrar, Straus & 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.
