The devil Screwtape, high-up in the Infernal Civil Service, writes to his nephew, Wormwood, a young demon new to securing the damnation of human souls. From the unique vantage point of the worldly-wise devil, C. S. Lewis follows the struggles, crises of faith and fresh convictions of one ordinary young man against Hell's perpetual cycle of corruption.

Written for J. R. R. Tolkien, this sly and ironic portrayal of human foibles and Hell's latest novelties is a masterpiece of satire. At once wildly comic, deadly serious and strikingly original, The Screwtape Letters is the most engaging account of temptation – and triumph over it – ever written.
