Meg Murry is a typical middle school student struggling with issues of self-worth who just wants to fit in. The daughter of two world-renowned physicists, she is intelligent and uniquely gifted, as is Meg's younger brother, Charles Wallace, but she has yet to realize it for herself. Complicating matters is the mysterious disappearance of Mr. Murry, which has left Meg devastated and her mother broken-hearted. Charles Wallace introduces Meg and her fellow classmate Calvin to three celestial beings (Mrs. Which, Mrs. Whatsit and Mrs. Who) who have journeyed to Earth to help search for their father, and together they embark on their formidable quest. Travelling via a wrinkling of time and space known as tessering, they are transported to worlds beyond their imagination where they must confront a powerful evil force. To make it back home to Earth, Meg must face the darkness within herself in order to harness the strength necessary to defeat the darkness rapidly enveloping the Universe.
