Prince Caspian

In this sequel to The Lion, the Witch, and the Wardrobe, four children are magically sucked back into Narnia while on their way to boarding school. They discover that they have been summoned by Prince Caspian, a child their age, who is fighting to avenge his father's death and become the true King of Narnia.

In this book, the kids are at first very kid-like and interesting. Soon enough, the magic of Narnia has them acting like stuffy Kings and Queens again and they just aren't that interesting anymore. However, the bad guys are interesting and there's a fairly exciting one-on-one fight between Peter and the evil "King" Miraz. The most interesting characters, though, are the Badger and the Mouse. And of course, Aslan once again makes an appearance to help save the day.

One final note: this is the only book in the series (so far) that actually almost made me cry. A beautiful, unexpectedly emotional moment happens near the end. Huh, maybe I'm just a sucker for mice! Read it if you are a fan of Narnia!
