Meg Murry is the twelve-year-old heroine of the story. Unlike her beautiful mother, Meg is plain. She wears glasses and has braces on her teeth, and she thinks she is unattractive. She also regards herself as an oddball. She does poorly in school even though she is good at math and science. But she solves math problems in her own way rather than the way she is taught at school. Meg can be stubborn, impatient and angry, but these qualities come in useful when she has to resist IT. Meg also loves her brother Charles Wallace dearly, and it is this quality that enable her to win him away from IT. During the course of the novel, Meg learns that her individuality is an asset rather than a liability, and she also learns that she must take responsibility for saving Charles herself, rather than waiting around for others to do it.
