A milestone in the history of popular theology, the Screwtape Letters is an iconic classic on spiritual warfare and the power of the devil. This profound and 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 and is lost to the young devil. Dedicated to Lewiss friend and colleague J. R. R. Tolkien, the Screwtape Letters is a timeless classic on spiritual conflict and the invisible realities which are part of our religious experience.
