The theme in A Wrinkle in Time is a battle of Good vs Evil for control of the universe. Meg, Charles Wallace, Calvin and other "ordinary" humans represent the the good, while disembodied entities referred to as "Thing" or "IT" represents the evil. The story unfolds with the characters trying to conquer the evil. The ragtag trio help the children try to conquer evil by giving them advice. The children must find answers to their questions on their own and follow the path of love and fellowship. The underlying theme is the power of love. The author makes it "clear that the only way one defeats evil, hatred, and death is love, a love which grows through suffering and a free acceptance of danger."
