After reading “Harry Potter and the Order of the Phoenix” — and all of the four preceding novels — one has to wonder if author J.K. Rowling is really a part of the “muggle” world herself.

In the fifth Harry Potter adventure, “The Order of the Phoenix,” Rowling — much like all of her previous books — tells the clear, picturesque tale about the wizardry world in such compelling detail the reader believes it to be real.

Readers envision the North Tower of Hogwarts where Divination is taught, the elaborate fountain and the Ministry of Magic building, and see the dark and winged horses known as thestrals lurk in the Forbidden Forest.

It’s almost as if Rowling lives in this world of wizardry, writing her novels as she watches events unfold.

Harry Potter, once curious and awestruck by wizardry, has taken on a darker and angrier temperament.

He regularly shouts at Hermione and Ron, his best friends and fellow classmates, and gets into classroom spats with professors.

His feelings about past events have become self-absorbed. It was Harry who saved the Sorcerer’s Stone, defeated the basilisk and survived an attack by he-who-must-not-be-named in the graveyard following his resurrection.

Rowling has done something incredible here with Harry’s character — she has showed the complexity of the teenage years.

At times, Harry becomes a typical 15-year-old: Unruly, unsure and completely confused by the opposite sex. He and Ron even go as far as to tell Hermione to write a book about the inner workings of female minds — a book many men would love to get their hands on.

Harry’s unsure life is not all his fault, though. After he and Dumbledore, headmaster of Hogwarts, proclaimed he-who-must-not-be-named has returned, the Ministry of Magic made sure everyone thought they were lunatics, using the magic world newspaper to call Harry a liar and Dumbledore a fool.

The stories about Dumbledore couldn’t be more false.

In the past, he has done an admirable job of counseling Harry, but in “The Order of the Phoenix,” the true reason why the Dark Lord fears Dumbledore is revealed: He is the most powerful wizard alive.

As one the pictures of an old headmaster put it, “I disagree with Dumbledore on many counts … but you cannot deny he’s got style.”

Despite its moments of humor, this book is darker than the previous ones — even the fourth book where he-who-must-not-be-named kills a promising student. Harry’s connection to he-who-must-not-be-named is deeper than anyone expected now that the Dark Lord is regaining full strength, and Harry is haunted by visions the Dark Lord sees.

When he-who-must-not-be-named is extremely angry or elated, Harry’s scar burns to the point where he becomes physically ill.

In his sleep, Harry sees horrible things. But, if Harry can get inside the head of he-who-must-not-be-named, then can the opposite happen? Can he-who-must-not-be-named control Harry?

This is the question concerning “The Order of the Phoenix,” the secret group who has formed to fight against the Dark Lord. Because of their worries, they tell Harry nothing, which only fuels his anger.

As Rowling warned, a main character is lost in the battle against the Dark Lord, revealing a depth of emotion not seen in the first four installments.

Because of her descriptive language and revealing dialogue, “The Order of the Phoenix” is nothing short of stellar, and is a perfect installment to the series.
