Meg Murry, the protagonist. At the age of thirteen, Meg is going through an awkward phase. Her figure is gangly and her hair stringy; she wears both braces and glasses. Moreover, she has a quick temper that marks her as “unfeminine.” Because Meg is not a conventionally “good” student, her teachers assume that she is “slow.” They are sadly mistaken; Meg has mastered short-cuts in mathematics. Understandably, her ability makes her stubborn and frustrated when she is asked to work problems in the traditional, roundabout way. Meg is ashamed of her faults, but as the story progresses, she learns that these “faults” are her greatest assets.
Charles Wallace Murry
Charles Wallace Murry, Meg’s younger brother. Like Meg, Charles is considered to be “slow.” He seldom talks around people outside his family and did not speak at all until the age of four. When he does talk, however, his vocabulary and syntax are those of an adult. Besides being highly intelligent, Charles Wallace is thoughtful beyond his five years. In the first chapter, for example, he rises from bed during a storm to make cocoa and sandwiches for his mother and sister, who have been awakened by the thunder.
