John Granger is an excellent writer, and a pleasure to read. All of his books on Harry Potter enable one to find new levels of meaning in the series. How Harry Cast His Spell is the newest edition of his books emphasizing the series' spiritual content. Unlocking Harry Potter and the Deathly Hallows Lectures are more aimed at discussing the series' literary aspects. Do not feel that this is just a rehash of Looking for God in Harry Potter, its previous edition. Although there are many of the same chapter titles, and some material is from the earlier edition, there is ample new coverage of The Deathly Hallows' spiritual aspects. There are some of the same helpful charts found in Looking for God in Harry Potter, but there are more, and fresh insights that allow you to say "Hey, I didn't notice that" the first (or second) time you read the series. For example, note the light ball of the Deluminator entering Ron's chest (near his heart) illuminating his spirit on Christmas morning, before he went back to his friends in the Forest of Dean. John Granger has a talent for discussing very weighty topics in an easy, enjoyable manner. There is a world of difference between Granger, and Kern's The Wisdom of Harry Potter (valuable reading, but a hard slog in comparison). Reading John Granger will enrich your experience of the Harry Potter series and your view of the world.
