A Wrinkle in Time (by Madeleine L'Engle)

Meg's father, an eminent physicist, has been missing for two years. One night a strange old woman, Mrs. Whatsit, appears, "blown off course" while she, along with Mrs. Who and Mrs. Which, was tessering, or taking a shorcut through time and space.

They take Meg, her little brother Charles Wallace, and their new friend Calvin, to rescue Dr. Murray, who is a prisoner on a planet ruled by IT, a giant pulsating brain that controls the minds of everyone on the planet. Charles Wallace also falls under IT's control, and when Meg finds her father, she discovers that he is not the invincible protector she thought he was. She must not only come to terms with this realization, but find a way to rescue them both.

For many children, reading A WRINKLE IN TIME is a turning point in their intellectual lives, opening to them worlds of science and literary complexity. Those who like action and adventure enjoy its science fiction story, filled with strange creatures and Meg's showdown with IT. Preteens of both sexes can relate to the coming-of-age theme, with a hint of romance, and commentary on the value of individuality over conformity. And kids who aren't terribly popular enjoy watching an outcast become a hero, and doing so by finding that her faults are also her strengths.

Grown scientists who read the book as a child recall it as being the first book that encouraged openness to imaginative speculation, the root of all scientific inquiry and creativity. Parents who want to expose their children to women and girls who are passionate about math and science would do well to slip their child a copy of this book. Not only do Meg and her mother fit this particular bill, but it is Meg who wages the battle between good and evil.
