I have an impression of each book in my head, and it turns out those impressions are mostly wrong. For some reason I remember Prince Caspian as being a lot of walking in the woods, when in fact the characters don't spend that much time walking in the woods at all.
This is one of my favorite in the Narnia series. I especially liked Caspian's backstory (which I had completely forgotten) this time around. It's like a little adventure tale inside an adventure tale.
