C. S. Lewis is one of the best-loved and most engaging Christian writers of recent times, and he continues to be a powerful defender of the faith. It is in his imaginative fiction that his genius finds its fullest expression and makes its most lasting theological contribution. Famously, Lewis had friends who, like him, employed powerfully creative imaginations to explore the profundities of Christian thought and their struggles with their faith. These illuminating essays on C. S. Lewis, J. R. R. Tolkien, Charles Williams, Dorothy L. Sayers, Rose Macaulay, and Austin Farrer are written by an international team of Lewis scholars.
