Author David Colbert has done a great job in THE HIDDEN MYTHS book. Focusing on the creatures, characters and other hidden meanings within the Potter series of books, Colbert has created a book that is both easy to read and follow for all HP fans. The map is a fun addition. With Book 7 still a long way from being published, I especially found it especially entertaining to finish this book and then immediately read the new ULTIMATE HARRY POTTER TRIVIA BOOK by author Daniel Lawrence to test how much I really know (or should I say "don't" know) about Harry Potter and Books 1-6. Excellent companion book. Being both a librarian and Harry fan, I highly recommend.
