Nothing especially interesting has ever happened to Sandy and Dennys, the run-of-the-mill twins in the extraordinary Murry family. Nothing, that is, until the bitter cold afternoon when, fooling around in their parents' lab, they type on the computer: TAKE ME SOMEPLACE WARM . . . SOMEPLACE WARM AND SPARSELY POPULATED . . . Suddenly Sandy and Dennys are in a harsh desert land. Many Waters continues the distinguished and popular Time Trilogy, made up of A Wrinkle in Time, A Wind in the Door, and A Swiftly Tilting Planet.
