Modeled after John Bunyan's famous Pilgrim's Progress, C. S. Lewis's Pilgrim's Regress represents a number of firsts for Lewis -- the first book he wrote after his conversion to Christianity, his first book of fiction, and the first book he published under his own name. This splendid annotated edition, produced in collaboration with the Marion E. Wade Center in Wheaton, Illinois, helps readers recover the richness of Lewis's allegory. Often considered obscure and difficult to read, The Pilgrim's Regress nonetheless remains a witty satire on cultural fads, a vivid account of spiritual dangers, and an illuminating tale for generations of pilgrims old and new. Editor David C. Downing's critical introduction provides needed biographical and cultural context for fully appreciating The Pilgrim's Regress. Downing relies throughout both on his own expertise and on previously unpublished sources from Lewis himself to identify allusions to other authors, translate quotations, and explain humor hidden within Lewis's text. Among the hundreds of annotations are references that draw parallels to Lewis's later works, including Mere Christianity, Surprised by Joy, and the Chronicles of Narnia.
