Write me a three paragraph essay on a wrinkle in time that includes the main characters.

In Madeleine L'Engle’s classic science-fiction novel, A Wrinkle in Time, three main characters embark on a journey through time and space to save the universe. These figures are Meg Murry, Charles Wallace Murry, and Calvin O’Keefe. Meg is the main protagonist of the book. She is a young girl of twelve years old living in a blended family. She is really intelligent but is often overlooked at school, due to her shyness. She is brave and willing to do whatever it takes to get her brother, Charles Wallace, back and save the universe. Charles Wallace is Meg’s five-year-old brother. He is incredibly intelligent and wise beyond his years. He is quite adept at reading people’s emotions and using his intuition to solve complex problems. He is taken away by a mysterious creature called IT, and it’s up to Meg and Calvin to save him. Calvin O’Keefe is a high school classmate of Meg’s. He is a popular and outgoing kid, yet he is deeply troubled by his own insecurities. He is also incredibly brave, often coming to Meg’s rescue. He is an essential part of the trio, as he helps Meg and Charles Wallace to solve the mystery of IT. The three characters must work together to save the universe in A Wrinkle in Time. Through their individual strengths and courage, they are able to traverse time and space and ultimately find and defeat IT. The bonds the three form along the way prove to be invaluable, as they rely on one another for strength during their difficult journey.
