A wrinkle in time

I read this book in third grade for a book report, and have loved it ever since. I suggest it be reread as you get older, as there are some interesting ideas to think about. I also recommend reading the entire series, they are all fantastic. My favorite however, is A Wrinkle in Time.

Meg is an awkward adolescent who does poorly in school, doesn't get along with her classmates, and especially doesn't get along with her principal, Mr. Jenkins. But that doesn't mean she isn't important in the battle against evil- and more importantly, to her family. When Mrs. Whatsit, the strangle lady that's been stealing sheets, shows up at her house in the middle of a dark and stormy night, Meg is off to other planets to rescue her father. Will she succeed?

I absolutely loved these books. After reading A Wrinkle in Time as a kid, I ate up everything else Madeleine L'Engle wrote. In an adult rereading, though, I was a bit surprised by the amount of Christian allegory... and literal Christianity (one mention of Jesus, lots of Hes and Hims, some Biblical quotes.) How did that get in there?
