Lord Voldemort has returned to power, and his wrath has been felt in both the Muggle and Wizarding worlds. Severus Snape, long considered an enemy of Voldemort and a member of Dumbledore's anti-Voldemort coalition, the Order of the Phoenix, meets with Narcissa Malfoy, mother of Harry's school rival Draco and wife of Lucius, an imprisoned Death Eater. Snape makes an Unbreakable Vow to Narcissa, promising to protect Draco.



Dumbledore collects Harry from his aunt and uncle's house. On their way to the home of Harry's best friend Ron Weasley and family, Harry and Dumbledore stop to persuade Horace Slughorn, former Potions teacher at Hogwarts, to return to teaching, and he finally agrees. Later, when shopping for schoolbooks, Harry and his friends Ron and Hermione follow Draco Malfoy to Dark Arts supplier Borgin and Burkes, where they overhear Draco insisting that the store-owner fix an unknown object. Harry is instantly suspicious of Draco, whom he believes to be a Death Eater like his father. The students return to school, and Dumbledore announces that Snape, the previous Potions teacher, will be teaching Defence Against the Dark Arts, while Slughorn will resume his post as Potions teacher.



Harry receives a used Potions textbook that once belonged to someone named "The Half-Blood Prince", which is heavily annotated and helps Harry excel in Potions. Believing that Harry needs to learn Voldemort's past to gain advantage in a foretold fight, Dumbledore schedules regular meetings with Harry in which they use Dumbledore's Pensieve to look at memories of those who have had direct contact with Voldemort. Harry learns about Voldemort's family and the influences that corrupted Voldemort, eventually leading him into dividing his soul into seven Horcruxes. Two of these, young Voldemort's diary and his grandfather's ring, have already been destroyed. Of the remaining, one resides in Voldemort, one resides in Voldemort's snake, one is Slytherin's locket, and the other two are suspected to be hidden in objects belonging to Hufflepuff, or Ravenclaw.



Ron acquires a new girlfriend, Lavender Brown, of whom Hermione is extremely jealous, and Harry feels stuck in the middle of his friends' bickering. Eventually, Harry falls in love with Ginny, Ron's sister, and Ron and Lavender break up, to Hermione's delight. Harry spends much of his time keeping up with his duties as Quidditch captain and following Draco Malfoy for any proof of suspicious actions, though he often cannot find him on his map of Hogwarts. Harry realizes that when Draco is not on the map, he is using the Room of Requirement on the seventh floor of Hogwarts, which transforms into whatever its user needs. Harry tries his best to get in to see what Draco is up to, but until he knows exactly what Draco is using the room for, he cannot gain access. Eventually Harry and Dumbledore leave Hogwarts to fetch and destroy the locket Horcrux, completion of which would make Voldemort one step closer to mortal. They journey to the middle of a treacherous sea into a cave with "known magic" that Voldemort visited when he was younger and reach the basin where the locket is hidden underneath a potion. Dumbledore drinks the potion and Harry fights off Voldemort's Inferi, an army of re-animated corpses. They take the locket and return to Hogwarts as quickly as possible. Dumbledore is quite weak, and when they reach Hogsmeade they can see that the Dark Mark, Voldemort's symbol, is visible above the astronomy tower.



When they arrive at the tower, Dumbledore uses his magic to freeze Harry in place while Harry remains hidden by his cloak of invisibility. Draco Malfoy arrives and disarms and threatens to kill Dumbledore, acting on his mission from Voldemort. Dumbledore tries to stall Draco by telling him he is not a killer, but then Snape bursts into the tower and kills Dumbledore, sending him flying over the edge of the tower. Because of Dumbledore's death, his spell on Harry is broken and Harry rushes after Snape to avenge Dumbledore's death. Snape reveals that he is the Half-Blood Prince and manages to escape. Later, Harry looks at the locket he and Dumbledore retrieved and realizes that it is not the real Horcrux. Inside the locket is a note from someone named "R. A. B."



After Dumbledore's funeral, Hermione explains to Harry that Snape was called the Half-Blood Prince because he had a Muggle father and a witch mother whose maiden name was Prince. Harry is devastated to think that he trusted and took help from the man who would turn out to be Dumbledore's murderer. He tells his friends he will not be returning to Hogwarts next year and will instead search out and kill Voldemort by destroying all of the Horcruxes. Ron and Hermione vow to join him.Short summary about harry potter and the half blood prince?
Have you read the books? You really just can't watch the movies without reading them. You seriously won't get it.



If you've read them, then there's not much for you to know except Quidditch wasn't involved as much, and Trelawny and Pansy were absent, there's no scene with the Prime Minister, Scrimgeour is completely absent, and there are two new scenes--one, during Christmas, Death Eaters come to the Burrow and set it on fire, so in Part 1 if you see a one story house Burrow, that's why. Also, at the end during the Battle of the Astronomy Tower they kind of expand on it a bit, they show Bellatrix chasing Neville in the Great Hall.Short summary about harry potter and the half blood prince?
