Harry Potter and the Half-Blood Prince

The sixth installment is released in various countries and sells 6.9 million copies on its first day. In Potter’s sixth year at school, he stumbles upon a mysterious textbook annotated by a person named the Half-Blood Prince. Potter searches for the book’s owner as well as a memory that may aid in defeating the dark Lord Voldemort. He learns more of Voldemort’s past and works alongside his school’s headmaster, Dumbledore, to prepare for battle. Rowling:

A lot happens in the sixth book and a lot of questions are answered. I really have a sense that we are nearly there and it is time for answers, not more questions and clues, although obviously there are a few clues as I am not quite finished yet.
