U.S. writer Madeleine L’Engle, beloved for her classic science-fiction classic A Wrinkle in Time, has died, her publicist said Friday. She was 88.

L’Engle died Thursday of natural causes at a nursing home in Litchfield, Conn.

L’Engle is the author of more than 60 books, including works for both children and adults.

But she is best known for A Wrinkle in Time, which won the 1963 Newbery Medal for excellence in children’s literature and has never been out of print since its publication.

Somewhat ironically, I just picked up and started re-reading “A Wrinkle in Time” just yesterday. Andy and I found the series on sale at the bookstore recently and decided that it would be nice to have the set. I haven’t read them in many years and I think I will enjoy making my way through them.
