This is yet another excellent book in the Harry Potter series. Order of the Phoenix has gone into a different direction than the other books and the tone is much more serious with a darker plot, not to mention Harry being angered throughout the book. But--like the others--I found the book hard to put down and finished it in about 2 days. JK still keeps Order of the Phoenix as suspenseful and humorous as the other 4 books, which makes it an excellent book, not to mention a must-read!
