I love the Narnian Chronicles too!
I thought I was the only one! I tried to pick my favorite and I had a very hard time. Finally I narrowed it down to three: The Last Battle, The Voyage of the Dawn Treader, and The Horse and His Boy.
C.S. Lewis is on my list of people that I want to meet in heaven. His ability to draw people into another world that exists only in his fervent imagination is incredible. Plus, it's not every day that you find fantasy novel (ny favorite genre and type of book) that is based upon Christianity instead of humanism, paganism, and witchcraft!
Please let me know if you've heard of any other Christian (or at least anti-sorcery) fantasy stories.
