The Horse and His Boy by C.S. Lewis (Book #3)
(Summary taken from the back of the book) “During the Golden Age of Narnia, when Peter is High King, a boy named Shasta discovers he is not the son of Arsheesh, the Colormene fisherman, and decides to run far away to the North–to Narnia. When he is mistaken for another runaway, Shasta is led to discover who he really is and even finds his real father.”
I liked this book a lot. The symbolism is not as apparent as in other books, but it is there and almost more meaningful. I definitely recommend it.
Recommendation: 12 and Up. 9 or 10 if read as a read-aloud.
