C. S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—takes readers on a spiritual journey through his early life and eventual embrace of the Christian faith. Lewis begins with his childhood in Belfast, surveys his boarding school years and his youthful atheism in England, reflects on his experience in World War I, and ends at Oxford, where he became "the most dejected and reluctant convert in all England." As he recounts his lifelong search for joy, Lewis demonstrates its role in guiding him to find God.
