On its first appearance The Screwtape Letters was immediately recognized as a milestone in the history of popular theology. Now in its 70th Anniversary Year & having sold over half a million copies it is an iconic classic on spiritual warfare & the power of the devil. This profound & striking narrative takes the form of a series of letters from Screwtape a devil high in the Infernal Civil Service to his nephew Wormwood a junior colleague engaged in his first mission on earth trying to secure the damnation of a young man who has just become a Christian. Although the young man initially looks to be a willing victim he changes his ways & is lost to the young devil. Dedicated to Lewiss friend & colleague J.R.R. Tolkien The Screwtape Letters is a timeless classic on spiritual warfare & the invisible realities which are part of our religious experience.
