I enjoyed this book very much. It tells a story of three children, Meg and Charles Wallace are siblings, and their friend Calvin, who go on an adventure to find Meg's missing father. They are helped by three mysterious, though lovable characters, Mrs. Whatsit, Mrs. Who, and Mrs. Which, who turn out to be much more than they appear. I especially liked the quotations from famous figures from around the world that are frequently elucidated by the mysterious ladies. The story has an underlying theme of the power of love and the strength it gives us all to face the world around us.
