Under Secretary Screwtape is writing advice to his protégé Wormwood as how to best tempt Wormwood’s “patient”, a human male living in England, into sin and draw him away from God. Written by C.S. Lewis and copyrighted 1942, this book is a masterpiece of satire and would fall under the category of Christian fiction.
C.S. Lewis wrote with a different style in this book than he tended to do with his other works; he uses less detail and no dialogue, as the book is told primarily through Screwtape’s letters to Wormwood. The Screwtape Letters is not an easy read, though it does flow very well; Lewis’ ideas and philosophies are quite profound. I would rate it at a hard read.
I would definitely recommend this book for ages 15+. There are some mature themes in it regarding the temptations that are recommended by Screwtape. An amazingly well written book with excellent literature, deep theological values, and thought-provoking chapters. 4.8 out of 5 stars.
