As much as I love the Chronicles of Narnia, I'm afraid that this one is not one of my favorites. The focus has shifted a bit too much for my tastes, and the main characters lack a lot of the charm that the original cast did- and seeing the two groups in juxtaposition only underscores this fact. 
 It's written by C.S. Lewis, and therefore it isn't bad by any stretch, but... alas, it is not as good as some of the others.
