The Chronicles of Narnia by C. S. Lewis

I first read these books when I was in the fourth grade. By the time I got to "The Silver Chair" I couldn't finish. I just couldn't follow the books. As an adult I picked up the books again. Now, I had a whole new perspective. This time around I saw all of the symbolism in the books. I understood why I wasn't able to follow along as well as a child. I enjoyed reading these books back to back and swimming in the symbolism found in the world C. S. Lewis had created.
