I really liked The Hobbit by J.R.R. Tolkien. I've read it three times through and I really like the 1978 film adaption of it. Its probably my favorite book even 'till this day, and has a very special place in my heart.
As a transcendentalist Christian, I believe humans are inherently good in nature, but are corrupted by society and the materialist world- which is not a thing of nature, thus civilization is plagued with sin.
