This is a great book! CS Lewis wrote this from the perspective of a senior devil who is writing letters to his nephew who is a novice devil. Each chapter is so insightful and thought provoking! Screwtape is the master tempter who has to give the novice insight in to how to lead souls to hell and the best way to get them there. Great book for discussion as there are so many moral and social issues that can be discussed. Highly recommend!
