For 50 years, 10 to 15 year olds have enjoyed Madeleine L'Engle's A Wrinkle in Time, and for 50 years, the book has been challenged by people who want it banned or censored. If you're interested in both the book and its history, I recommend the 50th Anniversary Commemorative edition of A Wrinkle in Time because of all of the bonus materials it provides about the book and its author and the praise and controversy that surrounded them. The special edition would also be a good gift for a L'Engle fan of any age who cherishes the book as a favorite. For more about the author, watch the About.com video profile of Madeleine L'Engle.
