The Silver Chair, because it was the first one I read, without knowing it was related to LWW (which I'd barely heard of). Got a particularly soft spot for Dawn Treader and The Horse and His Boy too.
Read Screwtape Letters and a few of Lewis' other straight religious books, but not tried his sci-fi stuff yet.
