C.S.路易斯,生於1898年，卒於1963年，是20世紀英國一位具有多方麵天纔的作傢。他26歲即登牛津大學教席，被當代人譽為“最偉大的牛津人”。1954年他被劍橋大學聘為中世紀及文藝復興時期英語文學教授，這個頭銜保持到他退休。

他的一生被稱為“三個c.s.路易斯”,意思是他在不到65歲時去世為止，完成瞭三類很不相同的事業：一是傑齣的牛津劍橋大學文學史傢和批評傢，代錶作包括《牛津英國文學史·16世紀捲》。二是深受歡迎的科學幻想作傢和兒童文學作傢，代錶作包括“《太空》三部麯”和“《納尼亞傳奇》七部麯”。三是通俗的基督教神學傢和演說傢，代錶作包括《天路迴歸》、《地獄來鴻》、《返璞歸真》、《四種愛》等等。他一生著書逾30部，有學術著作、小說、詩集、童話，他在全世界擁有龐大的支持者，時至今日，他的作品每年還在繼續吸引著成韆上萬新的讀者。

On its first appearance, The Screwtape Letters was immediately recognized as a milestone in the history of popular theology and has since sold more than a quarter of a million editions. Now stunningly repackaged and rebranded as part of the Signature Classics range. A masterpiece of satire, this classic has entertained and enlightened readers the world overwith 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 gives us the correspondence of the worldly wise old devil to his nephew Wormwood, a novice demon in charge of securing the damnation of an ordinary young man. Dedicated to Lewis's friend and colleague J.R.R. Tolkien, The Screwtape Letters is the most engaging account of temptation -- and triumph over it -- ever written.
