Clive Staples Lewis was a British writer and lay theologian. He is best known for his works of fiction, especially The Screwtape Letters, The Chronicles of Narnia, and The Space Trilogy, and for his non-fiction Christian apologetics, such as Mere Christianity, Miracles, and The Problem of Pain. The books that make up The Chronicles of Narnia have sold the most and have been popularised on stage, TV, radio, and cinema.

C.S. Lewis also wrote several popular novels including the science fiction Space Trilogy for adults and the Narnia fantasies for children. Most deal implicitly with Christian themes such as sin, humanity's fall from grace and redemption. The Chronicles of Narnia is a series of seven fantasy novels for children and is considered a classic of children's literature. Written between 1949 and 1954, and illustrated by Pauline Baynes, the series is C.S. Lewis's most popular work, having sold over 100 million copies in 41 languages.
