I can’t possibly tell you how I came to write it. It was simply a book I had to write. I had no choice. And it was only after it was written that I realized what some of it meant. 
L’Engle’s work reflects both her religious beliefs and her interest in popular science. She maintained a thirty year association with The Cathedral Church of Saint John the Divine, beginning as a volunteer librarian and later as writer-in-residence for many yearsOne of her noted sayings was that when she had something to write that was too hard for adults to understand, she wrote it for children. L’Engle was also noted for her generosity in sharing her expertise with aspiring writers.
