Modeled after John Bunyan's famous Pilgrim's Progress, C. S. Lewis's Pilgrim's Regress (1933) 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 brand-new annotated edition helps readers recover the richness of Lewis's original allegory. Often considered obscure and difficult to read, The Pilgrim's Regress nonetheless remains a rollicking satire on modern cultural fads, a vivid account of contemporary spiritual dangers, and an illuminating tale for generations of pilgrims old and new. Editor David C. Downing relies both on his own expertise and on previously unpublished sources from Lewis himself to identify allusions to other authors, translate quotations, and explain inside jokes hidden within Lewis's text.
