Fifty years ago, Madeleine L'Engle introduced the world to A Wrinkle in Time and the wonderful and unforgettable characters Meg and Charles Wallace Murry, and their friend Calvin O'Keefe. Now their first three adventures are together in one volume. In the Newbery Award winner A Wrinkle in Time, the children learn that Mr. Murry has been captured by the Dark Thing, and they must time travel to Camazotz to save him. In A Wind in the Door, Meg, Calvin and Mr. Jenkins (their grade school principal) must travel inside C.W. and battle to save Charles's life—as well as the balance of the universe. And in A Swiftly Tilting Planet, Meg's brother Charles Wallace has twenty-four hours to stop the tragedy of nuclear war from occurring. Read the iconic novels that continue to inspire millions of fans around the world.
