His books have sold millions and include classics like Mere Christianity, The Screwtape Letters, and The Lion, the Witch and the Wardrobe. Yet C. S. Lewis was not always a literary giant of Christian faith. How did he evolve from staunch atheism to become one of the most beloved and renowned Christian authors of our time? For C. S. Lewis enthusiasts and students alike, this book offers a unique look at Lewis's personal journey to faith and the profound influence it had on his life as a writer. Written by Professor David C. Downing, author of the critically acclaimed Planets in Peril, this thoughtful book is a delight.
