Query: Harry Potter and the Order of the Phoenix

This book is by far the greatest book that I have ever read. Harry still goes through his usual conflicts with his aunt and uncle, but fortunitely he does not stay at their home for the entire summer. Harry has even more problems to cope with in this book than any of the others, especially since most of the students at Hogwarts beleive him to be some stupid, lying, show-off. He goes through a lot of pain in the book, ending up losing one of the people that he cares for most. This entrancing book really keeps the reader's interest.
