C.S.路易斯,生于1898年，卒于1963年，是20世纪英国一位具有多方面天才的作家。他26岁即登牛津大学教席，被当代人誉为“最伟大的牛津人”。1954年他被剑桥大学聘为中世纪及文艺复兴时期英语文学教授，这个头衔保持到他退休。

他的一生被称为“三个c.s.路易斯”,意思是他在不到65岁时去世为止，完成了三类很不相同的事业：一是杰出的牛津剑桥大学文学史家和批评家，代表作包括《牛津英国文学史·16世纪卷》。二是深受欢迎的科学幻想作家和儿童文学作家，代表作包括“《太空》三部曲”和“《纳尼亚传奇》七部曲”。三是通俗的基督教神学家和演说家，代表作包括《天路回归》、《地狱来鸿》、《返璞归真》、《四种爱》等等。他一生著书逾30部，有学术著作、小说、诗集、童话，他在全世界拥有庞大的支持者，时至今日，他的作品每年还在继续吸引着成千上万新的读者。

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.
