Query: A wonderful book. - a review from a non-believer

I classify myself as agnostic. I am skeptical about the existence of God, but I don't rule it out entirely. I bring this up because this book is based solely upon the belief in God and (conversely) the Devil.The entire book is a one-sided view of a correspondence from an aging devil to his apprentice devil protege. The aging devil, named Screwtape, dispenses advise and wisdom gained from years as a tempter of humans.From this point of view, the reader gets a truly horrifying and entertaining view of one's own life and pursuits. I still don't profess a belief in God, but now I am beginning to believe in devils.
