J. K. 羅琳（J. K. Rowling, 1965- ），英國女作傢，自小喜歡寫作，當過短時間的教師和秘書。二十四歲那年，她在前往倫敦的火車旅途中萌生瞭創作“哈利·波特”係列小說的念頭。七年後，《哈利·波特與魔法石》問世，之後她陸續創作瞭《哈利·波特與密室》《哈利·波特與阿茲卡班囚徒》《哈利·波特與火焰杯》《哈利-波特與鳳凰社》《哈利·波特與“混血王子”》和《哈利·波特與死亡聖器》，完成瞭該係列的創作，在全球颳起一股股“哈利·波特”颶風，在世界範圍內掀起規模宏大的“哈利·波特”閱讀狂潮。另外，在此期間，她還因為慈善事業而先後完成瞭《神奇動物在哪裏》和《神奇的魁地奇球》這兩部與“哈利·波特”係列相關的圖書，最新完成的作品是《詩翁彼豆故事集》。

J.K.羅琳與她的丈夫及三個孩子生活在愛丁堡，一邊盡享傢庭生活的幸福，一邊文學創作。

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 at 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.
