Plot
At Hogwarts, Harry and Ron borrow textbooks from the school for Slughorn's Potions class. The previous owner of Harry's copy, "the Half-Blood Prince", has annotated the book with additional instructions and spellcraft that allow Harry to excel in class and win a vial of the luck potion, Felix Felicis. Ron becomes a Gryffindor Quidditch hero, attracting the love of Lavender Brown, leaving Hermione heartbroken. Harry is similarly distraught over Ginny's attraction to Dean Thomas. Harry spends Christmas Break with the Weasleys; while he is discussing the situation at Hogwarts with other Order of the Phoenix members, the Death Eaters attack and try to kidnap Harry; the wizards are able to keep everyone safe but the Burrow is burned to the ground.
Draco continues to elude Harry while perfecting the use of a Vanishing Cabinet inside the Room of Requirement. Harry suspects Draco is behind two attempts on Dumbledore's life: one through a cursed necklace, and another through a bottle of poisoned mead. Seeking revenge, Harry duels Draco and uses a curse from the Half-Blood Prince's book which severely injures Draco. Snape heals Draco while Harry retreats. Ginny convinces Harry to let her hide the book in the Room of Requirement to prevent him from using it again, and kisses him.
During private meetings, Dumbledore shows Harry memories of young Tom Riddle (Voldemort) and reveals Slughorn retains a memory critical to Voldemort's defeat from Slughorn. Harry manages to retrieve the memory using Felix Felicis. The memory reveals that Voldemort had been seeking information on Horcruxes, devices that safeguard a portion of the creator's soul, thereby granting him immortality until the Horcrux is destroyed. Dumbledore believes Riddle created seven Horcruxes, of which five remain to be destroyed before Voldemort becomes mortal. After learning the location of another Horcrux, Dumbledore requests Harry's help to retrieve it. Deep inside a seaside cave, Harry is forced to make Dumbledore drink a foul, mind-altering liquid that hides the Horcrux, a locket. Though weakened by the liquid, Dumbledore is able to defend them from a horde of inferi and apparates himself and Harry back to Hogwarts. There, Dumbledore first tells Harry to fetch Snape for help, but tells him to hide when footsteps approach.
Draco appears and admits Voldemort has chosen him to kill Dumbledore, but is unable to follow through. Snape arrives, motions to Harry to stay hidden, and joins the throng of Death Eaters cheering Draco on. To Harry's horror, Snape then casts the Avada Kedavra spell to murder Dumbledore and then escapes the castle with the other Death Eaters. In their wake, they cast the Dark Mark and wreck the Great Hall and Hagrid's Hut. Harry tries to stop them, but Snape deflects his spells and stuns Harry. As Snape departs, he reveals that he is the Half-Blood Prince. While Hogwarts mourns Dumbledore's death, Harry reveals to Ron and Hermione that the locket Horcrux was a fake. The locket contains a message from an "R.A.B." stating he has already taken the real Horcrux and seeks to kill Voldemort. Harry and his friends vow to seek out R.A.B. and the remaining Horcruxes instead of returning for their seventh year.
