Harry Potter and the half-blood prince

In the previous book, Harry Potter and the Order of the Phoenix, the last chapter, titled 'The Second War Begins,' started: 'In a brief statement on Friday night, Minister for Magic Cornelius Fudge confirmed that He Who Must Not Be Named has returned to this country and is once more active. 'It is with great regret that I must confirm that the wizard styling himself Lord ... well, you know who I mean ... is alive and among us again,' said Fudge.' In the midst of the battle of good and evil described in "The Order of the Phoenix", the sixth of the hugely popular Harry Potter novels takes up the story of our hero's sixth year at Hogwarts School of Witchcraft and Wizardry, with Voldemort's power and followers increasing day by day. This is the adult edition.
