Madeleine L'Engle wrote children's and young adult fiction that combines family stories, science fiction, fantasy and questions about faith and the universe. A Wrinkle in Time follows Meg Murry, her brother Charles Wallace and their friend Calvin O'Keefe as they travel through space in search of Meg's missing scientist father, encountering the controlling intelligence IT on the planet Camazotz. The story continues through the Time Quintet, where the Murry and O'Keefe families face problems involving time, cosmic scale and moral responsibility. L'Engle also wrote more realistic family novels and interconnected books for older readers. Her fiction is adventurous and idea-driven, using scientific concepts and spiritual questions without treating either as background decoration. It fits children's science fiction, time-travel fantasy and family adventure alongside writers such as Susan Cooper and Diana Wynne Jones. Read more Less
