Madeleine L'Engle is a famous writer of fantasy for young people. Her best-known book, A Wrinkle in Time, has been loved by generations of readers and lauded by critics, but some people claim that L'Engle's writing endorses a New Age philosophy and they have asked that her books be removed from schools and libraries. Author Marilyn McClellan discusses L'Engle's life and beliefs and analyzes two of her best known books. She also explores the history and present state of book censorship and helps readers form their own opinions about whether books should be banned.
