Query: Harry Potter and the Order of the Phoeinx

Harry Potter and the Order of the Phoenix was an excellent book!! In my opinion it was the best Harry Potter book yet. J.K. Rowling keeps you wondering when Voldemort will surface just long enough to build suspense. The characters are changing and growing up and Rowling does an excellent job showing this! I plan to reread the book again, simply for fun!!
