<P> In A Wind in the Door (1973), Meg is much happier in school than previously, in part because of her friendship with Calvin . However, she is deeply worried about Charles Wallace, who has difficulty getting along with students and teachers and suffers from a mysterious illness involving his mitochondria . Meg tries to intervene on his behalf with Mr. Jenkins, the school principal, whom she still resents due to past conflicts . Meg learns to love and appreciate Jenkins, however, when she is given the task of "Naming" him and distinguishing between the principal and his Echthroi doppelgangers . Meg, Mr. Jenkins, Calvin, and a "singular cherubim" are then sent inside one of Charles Wallace's mitochondria to turn the tide against the Echthroi, the forces of Entropy and "Unnaming ." Meg learns to appreciate the cosmic harmony and interdependency of macrocosm and microcosm . Meg also learns to "kythe" with Calvin and others, communing with them essentially by telepathy . </P> <P> In Many Waters (1986), Meg is about nineteen years old, in college, and writing a paper titled "The Million Doller (sic) question: the chicken or the egg, amino acids or their polymers ." She is said to have a "long commute" to school, but apparently does not mind this because she "likes to drive ." At the dentist with her mother and Charles Wallace as the book begins, Meg appears only in the book's final two pages . Her brothers Sandy and Dennys spend most of the story in the time of Noah, but refer occasionally to Meg and Charles Wallace as the "special ones" in the family . </P> <P> Meg marries Calvin between the events of Many Waters and those of A Swiftly Tilting Planet . She gives birth to her first child with Calvin, Polyhymnia (called Poly and eventually Polly) shortly after the later book . Although she has not earned a doctorate, she is a mathematician who helps Calvin with his work in marine biology . As of the later books about Polly, Meg is said to be "restless" and considers going back to school . Having outgrown her awkward "ugly duckling" adolescence, she is considered beautiful as an adult, with long chestnut hair and contact lenses . </P> <P> In A Swiftly Tilting Planet (1978), Meg is heavily pregnant and at her parents' house for Thanksgiving, along with Sandy and Dennys . Meg is living in a furnished apartment near the hospital where Calvin works, but it is said that they often visit Meg's parents on weekends . At the time of the book, Calvin is in London presenting a paper, but his mother, Branwen O'Keefe, reluctantly visits the Murrys . When Meg's father gets a phone call from the President of the United States about a threat of nuclear war, Mrs. O'Keefe recites a rune with which she expects Charles Wallace to prevent the end of the world . As Charles Wallace travels in time to change key events in the past, Meg supports his efforts by kything with him . Meg mourns the death of Fortinbras, the family dog mentioned in A Wrinkle in Time and A Wind in the Door, but welcomes a new dog, Ananda, into the family . She also receives a call from Calvin during the course of the book, during which he reassures her and tells her he loves her . In A Swiftly Tilting Planet, Meg is a stunningly beautiful young woman, and is pregnant with her daughter, Polly O'Keefe, although neither the baby's name nor gender is given . </P>
