Query: The darkest, and in some ways the best, of all seven

Everyone (children and adults) loves a great "good vs. evil" story. I often think that something that everyone raves about just can't be as good as the say, but Harry Potter exceeds the reviews.The incredibly rich detail in all the Harry Potter novels is really the best aspect of the story. JKR creates a whole world that readers can't forget about. There many subplots, but JKR keeps them all straight.While this book is definitely dark, JKR manages to keep many humorous and lighter aspects of the previous books, parts not shown in the movie. This book pulls you in and will not let you go, as it is the cliff-hanger before the finale. It will leave you crazy until you read Harry Potter and the Deathly Hallows.I can't tell you how great all the books in this series are, you'll have to read them for yourself. Harry Potter is the new Star Wars, the new Lord of the Rings. It already is a legend.
