A Wind In The Door is a fantastic adventure story involving Meg Murry, her small brother Charles Wallace, and Calvin O'Keefe, the chief characters of A Wrinkle In Time. The seed from which the story grows is the rather ordinary situation of Charles Wallace's having difficulty in adapting to school. He is extremely bright, so much so that he gets punched around a lot for being "different." He is also strangely, seriously ill (mitochondritis -- the destruction of farandolae, minute creature of the mitochondria in the blood). Determined to help Charles Wallace in school, Meg pays a visit to his principal, Mr. Jenkins, a dry, cold man with whom Meg herself has had unfortunate run-ins. The interview with Mr. Jenkins goes badly and Meg worriedly returns home to find Charles Wallace waiting for her. "There are," he announces, "dragons in the twins' vegetable garden. Or there were. They've moved to the north pasture now." Dragons ? Not really, but an entity, a being stranger by far than dragons; and the encounter with this alien creature is only the first step that leads Meg, Calvin, and Mr. Jenkins out into galactic space, and then into the unimaginably small world of a mitochondrion. And, at last, safely, triumphantly, home.

Madeleine L’Engle (1918–2007) was born in New York City and attended Smith College. She wrote more than 60 books, the most famous of which is A Wrinkle In Time (1962), winner of the Newbery Award in 1963. L’Engle continued the story of the Murry family from A Wrinkle In Time with seven other novels (five of which are available as A Wrinkle In Time Quintent from Square Fish). She also wrote the famous series featuring the Austin family, beginning with the novel Meet The Austins (1960). L’Engle revisited the Austins four more times over the next three decades, concluding with Troubling a Star in 1994. The story of the Austins had some autobiographical elements, mirroring Madeleine’s life and the life of her family. Madeleine L’Engle’s last book, The Joys of Love, is a romantic, coming-of-age story she wrote back in the 1940s, and is being published by FSG.
