A Wrinkle In Time by Madeleine L'Engle

Meg Murray, her little brother Charles Wallace, and their mother are having a midnight snack on a dark and stormy night when an unearthly stranger appears at their door. He claims to have been blown off course, and goes on to tell them that there is such a thing as a “tesseract”, which, if you didn’t know, is a wrinkle in time. Meg’s father had been experimenting with time-travel when he suddenly disappeared. Will Meg, Charles Wallace, and their friend Calvin outwit the forces of evil as they search through space for their father?   

In 1962, Madeleine L’Engle debuted her novel A Wrinkle in Time, which would go on to win the 1963 Newbery Medal. Bridging science and fantasy, darkness and light, fear and friendship, the story became a classic of children’s literature and is beloved around the world.
