The "Harry Potter" series by J.K. Rowling is a beloved seven-book fantasy saga that chronicles the life of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, during their years at Hogwarts School of Witchcraft and Wizardry.
Here's a summary of the complete story, book by book:
1. Harry Potter and the Sorcerer's Stone (Philosopher's Stone in the UK): We are introduced to eleven-year-old Harry Potter, who lives a miserable life with his abusive aunt and uncle, the Dursleys, after his parents died when he was a baby. On his eleventh birthday, he discovers he is a wizard and is invited to attend Hogwarts. He learns his parents were murdered by Lord Voldemort, and that he miraculously survived Voldemort's killing curse, leaving him with a lightning-bolt scar and a legendary status in the wizarding world. At Hogwarts, he befriends Ron Weasley and Hermione Granger. They uncover a plot to steal the Sorcerer's Stone, which grants immortality, and defeat Professor Quirrell, who is secretly possessed by Voldemort.
2. Harry Potter and the Chamber of Secrets: During his second year, strange attacks begin at Hogwarts, leaving students petrified. Messages written in blood warn of the "Chamber of Secrets" being opened, releasing a monster to purge the school of Muggle-borns. Harry discovers he can speak Parseltongue (the language of snakes), leading many to suspect him. He, Ron, and Hermione discover the Chamber is linked to the school's founder, Salazar Slytherin, and is being opened by a diary that possesses Ron's sister, Ginny. Harry confronts Tom Riddle, a memory of Voldemort, and defeats the Basilisk, a giant snake, with the sword of Godric Gryffindor, destroying a piece of Voldemort's soul (a Horcrux).
3. Harry Potter and the Prisoner of Azkaban: In his third year, Harry learns that Sirius Black, a notorious mass murderer and Voldemort's supposed right-hand man, has escaped from Azkaban prison and is believed to be hunting Harry. Dementors, soul-sucking creatures, are assigned to guard Hogwarts. Harry learns the Patronus Charm to defend himself. Through twists and turns, Harry discovers that Sirius is his innocent godfather, framed by Peter Pettigrew, who is still alive and disguised as Ron's pet rat, Scabbers. They manage to expose Pettigrew, but he escapes, and Sirius remains a fugitive.
4. Harry Potter and the Goblet of Fire: Harry's fourth year sees Hogwarts host the Triwizard Tournament, a dangerous inter-school competition. Despite being underage, Harry's name is mysteriously entered. He competes in three perilous tasks against champions from other schools. The tournament culminates in a dramatic twist: the final task is a trap, leading Harry to a graveyard where Voldemort, with Peter Pettigrew's help, is resurrected in his full, terrifying physical form. Voldemort duels Harry, but Harry escapes, though fellow champion Cedric Diggory is killed. The wizarding world is forced to acknowledge Voldemort's return.
5. Harry Potter and the Order of the Phoenix: In his fifth year, the Ministry of Magic actively denies Voldemort's return, discrediting Harry and Dumbledore. Dolores Umbridge, a tyrannical Ministry official, is appointed to Hogwarts, systematically undermining Dumbledore and teaching useless "defensive" magic. Harry forms Dumbledore's Army, a secret group to teach practical defensive spells. Harry is plagued by visions of Voldemort and experiences a growing connection to his mind. The book culminates in a battle at the Ministry of Magic, where Harry learns of a prophecy connecting him and Voldemort. Sirius Black is tragically killed in the fight.
6. Harry Potter and the Half-Blood Prince: Harry begins his sixth year, now aware of the prophecy and his ultimate role. Dumbledore begins private lessons with Harry, revealing Voldemort's past and the existence of Horcruxes – objects containing fragments of Voldemort's soul, which must be destroyed to kill him permanently. Harry suspects Draco Malfoy is involved in dark activities. Snape becomes the new Defense Against the Dark Arts teacher. The book ends with Dumbledore and Harry retrieving a supposed Horcrux, only for Dumbledore to be killed by Severus Snape on top of the Astronomy Tower. Harry discovers the retrieved Horcrux is a fake.
7. Harry Potter and the Deathly Hallows: Harry, Ron, and Hermione abandon their final year at Hogwarts to hunt for and destroy the remaining Horcruxes. They face numerous challenges, including the Ministry's takeover by Death Eaters and the constant threat of capture. They uncover the existence of the Deathly Hallows: the Elder Wand, the Resurrection Stone, and the Cloak of Invisibility, which together are said to make one the "Master of Death." They eventually infiltrate Hogwarts, where the final battle against Voldemort and his forces takes place. Harry discovers that he himself is a Horcrux and must die to destroy the piece of Voldemort's soul within him. He sacrifices himself, but due to his mastery of the Deathly Hallows, he is able to return. In the ultimate showdown, Harry defeats Voldemort, who is killed when his own Killing Curse rebounds, as the Elder Wand's allegiance truly lies with Harry. The wizarding world is freed from Voldemort's tyranny.
The series concludes with an epilogue set nineteen years later, showing Harry, Ron, and Hermione, now adults with children, sending their own children off to Hogwarts, signifying a peaceful and hopeful future for the wizarding world.
