One of my favorite books is easily A Wrinkle in Time, by Madeleine L'Engle. I can't remember when I first read it, but when I went back to it a couple of years ago, I was struck by its prose and outstanding story.
What's more astonishing is that it was rejected dozens of times from publishers, before going on to win one of the major awards for YA literature. Moreover, it's still highly relevant to any teenager or young reader today.
- Madeleine L'Engle Herself: Reflections on a Writing Life, Madeleine L'Engle. This was a moderately useful book, as it contained some biographical elements.
- Listening for Madeleine: A Portrait of Madeleine L'Engle in Many Voices, Leonard Marcus. This is an astounding book, and I wish that each one of the authors that I've looked at had something similar. It's an entire book of oral histories, conducted with people who worked with or who were close with L'Engle. It's a fantastic source.
- Madeleine L'Engle: Short biographical sketch from the National Endowment for the Humanities.
- The Storyteller: Fact, fiction, and the books of Madeleine L’Engle. This is a fantastic article on the life of L'Engle, and Zarin does a great job parsing out the complexity of her character. It's well worth a read.
- Obituary. L'Engle's obituary from the New York Times, which provides some interesting details about her life.
- L'Engle, Madeleine. Biographical entry from the Encyclopedia of Science Fiction.
- ALA's Banned Books Page. The American Library Association's home page for their Banned Books week, which includes links to the lists of books that are frequently challenged and banned.
