This is also a good book (by the way all Harry Potter books are). During another summer with his Aunt Petunia and Uncle Vernon, Harry Potter and Dudley are attacked by dementors. After using magic to save Dudley and himself, Harry is expelled from Hogwarts but the decision is later cancelled. Harry is taken away by a group of wizards to Number 12, Grimmauld Place, the home of his godfather, Sirius Black. The house also serves as the headquarters of the Order of the Phoenix. Ron Weasley and Hermione Granger explain that the Order of the Phoenix is a secret organisation led by Hogwarts headmaster Albus Dumbledore, dedicated to fighting the evil Lord Voldemort and his followers, the Death Eaters.

WOW! AGAIN J K ROWLING HAD MADE A GREAT COMEBACK AFTER THE AMAZING BOOK OF GOBLET OF FIRE, HERE THIS TIME HARRY FACES PROBLEMS WHICH ARE BEYOND JUST CREATIVE FOR ANY WRITER TO THINK AND FASCINATING ENOUGH FOR ANY READER WHO IS READING HARRY POTTER FROM THE VERY BEGNNING. I AM REALLY LOOKING FORWARD FOR THE NEXT BOOK.

Amazingly written book. Harry Potter has always been a perfect blend of everything making it one of my favorite book. THE ORDER OF PHOENIX is Released around the world at precisely on minute past midnight, Harry Potter and the Order of the Phoenix was literally flying off the shelves, with over six million copies of the book selling in a mere twenty four hours! Within hours it became obvious that Harry Potter was going to be quickest selling book of all time. During the holidays, Harry is stuck with his awful relations who do everything in their power to make his life miserable. This is only made worse by the fact that his friends are being very distant with their correspondence and will not tell him much about where they are or what they were doing. The unpredictable happens and Harry is forced to use magic to get him out of a life-threatening situation. He is then faced with possible expulsion from school, which doesn't really make his dismal mood any better. Things are finally explained when Harry catches up with his friends, and his worst fears are confirmed as he realises that Voldemort is back, and very much alive. Subsequently, a secret organization is formed by people who wish to protect the wizarding (and Muggle) world from danger, and they plan to fight against Voldemort and anybody who sides with him.
