Harry trávi už šiesty rok na Rokfortskej čarodejníckej škole. Voldemortova moc rastie zo dňa na deň, jeho stúpencov pribúda. Kto je "polovičný princ"? Isté je len to, že to nie je ani Harry, ani Voldemort...Harry Potter and the Half-Blood Prince takes up the story of Harry Potter's sixth year at Hogwarts School of Witchcraft and Wizardry at this point as Voldemort's power and followers are increasing day by day, in the midst of this battle of good and evil. The author has already said that the Half-Blood Prince is neither Harry nor Voldemort. Intriguingly, the opening chapter of Harry Potter and the Half-Blood Prince has been brewing in J.K. Rowling's mind for 13 years. Harry Potter and the Order of the Phoenix, J.K. Rowling's fifth Harry Potter book, was released on 21st June, 2003, and was the fastest-selling book in history on the first weekend of its publication. All five Harry Potter books, Harry Potter and the Philosopher's Stone, Harry Potter and the Chamber of Secrets, Harry Potter and the Prisoner of Azkaban, Harry Potter and the Goblet of Fire, as well as Harry Potter and the Order of the Phoenix, have all been Number One bestsellers in the United Kingdom, the United States and around the world. J.K. Rowling has revealed three chapter titles from Harry Potter and the Half-Blood Prince to be: * Chapter Two: "Spinners End" * Chapter Six: "Draco's Detour" * Chapter Fourteen: "Felix Felicis" A Few Words from J.K. Rowling: "I am an extraordinarily lucky person, doing what I love best in the world. I'm sure that I will always be a writer. It was wonderful enough just to be published. The greatest reward is the enthusiasm of the readers." —J.K. Rowling.
