"The war against Voldemort is not going well: even Muggle governments are noticing. Ron scans the obituary pages of The Daily Prophet looking for familiar names. Dumbledore is absent from Hogwarts for long stretches of time, and the Order of the Phoenix has already suffered losses. And yet...

As in all wars, life goes on. Sixth-year students learn to Apparate, and lose a few eyebrows in the process. The Weasley twins expand their business. Teenagers flirt and fight and fall in love. Classes are never straightforward, though Harry receives some extraordinary help from the mysterious Half-Blood Prince.

So it's the home front that takes center stage in the multilayered sixth installment of the story of Harry Potter. Harry struggles to uncover the identity of the Half-Blood Prince, the past owner of a potions textbook he now possesses that is filled with ingenious, potentially deadly, spells. But Harry's life is suddenly changed forever when someone close to him is heinously murdered right before his eyes.

With Dumbledore's guidance, he seeks out the full, complex story of the boy who became Lord Voldemort, and thereby attempts to find what may be his only vulnerability."
