Meg Murry is a high school student, a defensive misfit who gets along best with her family and her friend Calvin O'Keefe. She wears glasses, has brown hair, and initially considers herself "repulsive-looking" and "dumb", although she is quite good at math. By the time of "A Wind in the Door", Meg is much happier in school than previously, in part because of her friendship with Calvin, but is deeply worried about Charles Wallace. In "naming" Mr. Jenkins, Meg learns to love and appreciate someone she has always resented. In the course of the story Meg also learns to "kythe" with Calvin, Proginoskes, and others, communing with them essentially by telepathy.
