Harry is waiting in Privet Drive. The Order of the Phoenix is coming to escort him safely away without Voldemort and his supporters knowing - if they can. But what will Harry do then? How can he fulfil the momentous and seemingly impossible task that Professor Dumbledore has left him?

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. Here are Hogwarts, Harry will search for the full and complex story of the boy who became Lord Voldemort — and thereby find what may be his only vulnerability.

Harry Potter is due to start his fifth year at Hogwarts School of Witchcraft and Wizardry. His best friends Ron and Hermione have been very secretive all summer and he is desperate to get back to school and find out what has been going on. However, what Harry discovers is far more devastating than he could ever have expected...
