-At school, Harry and Ron are admitted to Slughorn's potions class at the last minute and borrow the needed textbooks. The previous owner of Harry's copy, the "Half Blood Prince" has annotated the book with many instructions that allow Harry to excel.

Harry finds Hermione crying in the Astronomy Tower and he reveals he has feelings for Ron's sister Ginny.

Outnumbered, they give up on attacking Order members as Nymphadora Tonks and Remus Lupin arrive, and everyone, saddened, watches the Weasley home go up in flames.
-Suspicious that Draco is responsible for the attacks on Dumbledore's life, one of which nearly kills Ron, Harry confronts him and severely wounds him with the Sectumsempra curse from the Half Blood Prince's book. Harry, shocked that it causes Draco's chest to be cut open, retreats as Snape enters and helps Draco. Fearing the book may be filled with Dark Magic, Ginny and Harry hide the book in the Room of Requirement and that's where they share their first kiss.
-Dumbledore shows Harry memories of a young Tom Riddle and reveals that Slughorn retains a memory critical to Voldemort's defeat. Harry retrieves the memory, learning that Voldemort wanted info for creating Horcruxes. The Horcrux protects a portion of a creator's soul, granting immortality unless destroyed. 2 of the Horcruxes of Voldemort's have been destroyed: Tom Riddle's diary and Marvolo Gaunt's ring. Touching the ring, Harry has a vision of Voldemort, noticed by Dumbledore. After finding the possible location of another Horcrux, Dumbledore requests Harry's presence and help to retrieve it. They travel to a far away cave where Harry is forced to make Dumbledore drink a mind altering potion that hides the Horcrux, a locket. Weakened, Harry protects Dumbledore from an attack from Inferi and they both apparate back to the Astronomy Tower. Elsewhere, Bellatrix, Greyback and several other Death Eaters enter the castle with Draco's help.
-Upon arriving, Dumbledore tells Harry to fetch Snape but as he hears footsteps, tells Harry to hide. Draco reveals that he has been chosen by Voldemort to kill Dumbledore, but is unable to follow through. Snape arrives and performs the Avada Kedavra curse on Dumbledore, killing him. As Bellatrix casts the Dark Mark, Snape, Draco and the Death Eaters escape. She also sets about destroying the Great Hall and sets fire to Hagrid's hut. Snape overpowers Harry and reveals he is the Half-Blood Prince. Harry returns to the school to find the students standing around the lifeless body of their once headmaster. Together they destroy the Dark Mark to honor Dumbledore.
-Later on, Harry reveals to Ron and Hermione that the locket was a fake. The locket contains a message from R.A.B to Voldemort stating that had stolen the real Horcrux and was intending to destroy it. His dying wish was that when Voldemort meets his match that he will be mortal once more.
