In this updated edition, revised to include insights into all seven books of the Harry Potter series, John Granger-Christian, teacher of classic literature, and father of seven homeschooled children--explores the surprising reasons J. K. Rowling's books are so popular and examines what Rowling acknowledges are strong Christian themes throughout the Harry Potter series. Granger decodes the "secret message" of the Potter novels and reveals a set of spiritual insights that may explain why the books have captivated the imagination of an entire generation. Granger helps readers understand the classic literary devices used in the Potter books and contends that Rowling is writing in the tradition of Tolkien and C.S. Lewis. And he offers an answer to the often-asked question: Are the books just good reads, or do they nourish the soul as well?
