Wizards and muggles alike, take note! Author J.K. Rowling has conjured up a title for her sixth Harry Potter novel: Harry Potter and the Half Blood Prince. She's also spilled some tantalizing plot clues on her official Web site. "The Half Blood Prince is neither Harry nor Voldemort," Rowling wrote, "and that's all I'm saying on that subject until the book's published." She added that "certain crucial pieces of information in Book 6 were originally planned for [the second book] The Chamber of Secrets." However, she noted, both the second and sixth books "hold some very important clues to the ultimate end of the series." What a tease.
