5The Screwtape Letters by C.S. Lewis is a classic masterpiece of religious satire that entertains readers with its sly and ironic portrayal of human life and foibles from the vantage point of Screwtape, a highly placed assistant to "Our Father Below." At once wildly comic, deadly serious, and strikingly original, C.S. Lewis's The Screwtape Letters is the most engaging account of temptation-and triumph over it-ever written.
