I first read The Chronicles of Narnia when I was in grade school. A friend and I discovered the books in our sparse school library and competed to finish each book to see who could get the next one first. Our competition started when we were in seventh grade and we finished them the next year. It was a small Catholic school and we did not have Amazon back then.
The adventures that C. S. Lewis wrote about in the mythical land of Narnia offered good, clean reading. I have read them many times over the years and when I had children, I invested in a hardcover collection. I encouraged my kids to read them.
The second and fourth books (The Lion, the Witch and the Wardrobe and Prince Caspian) have been made into movies by Disney. I received Prince Caspian for my recent birthday and we finally all got together to watch it last night. Disney did a great job of capturing the magic, but read the books.
