War rages in the wizarding world as Harry begins private lessons with Dumbledore, diving into the Pensieve to trace Tom Riddle's past and uncover the secret of his immortality — the Horcruxes. Meanwhile, a battered Potions textbook annotated by the mysterious Half-Blood Prince makes Harry a star student, and Draco Malfoy is working on a terrible mission in the Room of Requirement.
