Harry Potter And The Half-Blood Prince

Harry Potter and the Half-Blood Prince is the sixth book in J. K. Rowling's Harry Potter series, first published in 2005. With Lord Voldemort's return now widely acknowledged, the wizarding world grows darker, and Harry begins a series of private lessons with Dumbledore built around memories that reveal Voldemort's history and the origins of his quest for immortality through Horcruxes — magical objects that each conceal a fragment of a split soul.

At Hogwarts, Harry excels in Potions with the unexpected help of a used textbook once owned by a student calling themselves the "Half-Blood Prince," whose handwritten spells and shortcuts fill its margins. Alongside the growing threat, the book follows Ron, Hermione and Harry through the ordinary turmoil of their sixth year — exams, friendships and first romances — while Draco Malfoy is seen acting strangely, carrying out a secret task for Voldemort inside the castle itself.

The novel builds to a tragic climax atop the Astronomy Tower, where Dumbledore is killed by Severus Snape, who is revealed as the Half-Blood Prince. The book ends with Harry resolving to leave Hogwarts and hunt down the remaining Horcruxes himself, setting up the series' final volume.
