Harry Potter and the Order of the Phoenix
Harry Potter, the leader of “The Order of the Phoenix,” is now a fifteen-year-old and he’s been writing his story from his point of view.
The darkest book in the Harry Potter series maybe this one. In fact, Voldemort and his Death Eaters play a very minor role this year during their return.
After the Ministry of Magic’s declaration of war, Harry Potter has to deal with two new opponents; Cornelius Fudge and Dolores Umbridge. Fudge is the director of the ministry and is unafraid to speak his mind. Dolores Umbridge is a woman who likes to cast spells on those she doesn’t like. She even forces Harry to speak with her in a different language because she can’t understand him.
The Order of the Phoenix is resurrected in this book, as well as Voldemort’s return. In addition to all of this, there are regular happenings at Hogwarts.
This more mature novel, which is darker and more serious than the earlier books in the series, shows how Harry deals with death and conflict while growing up.

Of all the Harry Potter books, what is the longest, and what is the shortest?
Order of the Phoenix (766 pages)
Out of all the books in the series, Order of the Phoenix is by far the longest. This book features Harry and his friends taking secret group classes together while trying to hide their activities from Umbridge.
Lord Voldemort also makes a return in this installment, which means there are many adventures and tribulations for Harry and others to deal with.
Since it’s so long, you may need weeks (or even months) to get through it unless you can devote that kind of time.
The Goblet of Fire (636 pages)
The Goblet of Fire was published in 2000, which became the basis for the movie “Harry Potter and the Goblet of Fire,” released in 2005. The fourth Harry Potter book that was released has a total of 636 pages. It’s the third-longest in the series.
The Half-Blood Prince (608 pages)
Harry Potter and the Half-Blood Prince contains 608 pages. It is the penultimate book of the series and was released in 2007.
During the Half-Blood Prince, Hogwarts is bombarded by Voldemort’s Death Eaters, while Harry must steel himself to fight. We also get a glimpse into Voldemort’s past.
This book should take you around 10 hours and 7 minutes to read if you are reading at an average speed of 250 words per minute.
The Deathly Hallows (607 pages)
Harry Potter and the Deathly Hallows is the second-longest book in the series. It’s also the final installment in the series, which is why it’s so long.
In this book, Harry’s friends have to search for Voldemort’s Horcruxes while simultaneously fighting the death eaters in a world that they’ve lost control of.
The final book in the series makes sense given how action-packed and fulfilling it is!
The Prisoner of Azkaban (317)
The Prisoner of Azkaban follows Harry discovering that Sirius Black escaped from prison.
This book should take you 7 hours and 15 minutes on average to read.
The Chamber of Secrets (251 pages)
Harry Potter and the Chamber of Secrets is the second installment of the franchise. Made up of 251 pages, it’s also one of the shorter books in the series. At 250 words per minute, it would take around 5 hours and 41 minutes to read if your goal was to finish without stopping.
The Sorcerer’s Stone/Philosopher’s Stone (223)
Harry Potter and the Sorcerer’s Stone is the shortest and first book of the franchise. You’ll finish it in 5 hours and 32 minutes. It’s also a great first read if you’re looking for an introduction to J.K Rowling’s world.
How long will it take to read all the Harry Potter books?
In total, an average of 68 hours (and 40 minutes) are necessary to read the Harry Potter series at a reading speed of 250 words per minute. If you’re not sure how long it would take in reality, that length of time should be relevant to your current reading rate.
