The Screwtape Letters (by C S Lewis)

'The Screwtape Letters' is classic Christian fiction by CS Lewis. He is probably best known for his 'Narnia' books for children, and also for Christian apologetics, such as 'Mere Christianity'.

This book is all written as letters from a senior demon to his nephew. They advise how to administer temptation most effectively. A clear Christian message is presented in this rather unusual form, and is all the more striking as a result.

I read this book before, many years ago. But I found it thought-provoking and enjoyable on re-reading.

Highly recommended.
