Sorry. Another post from me.
Just came across this AP story on MSNBC.com:
Harry Potter to survive to book No. 7: But author Rowling won't say if wizard survives to adulthood.
Not that it is a big surprise that Harry will live to Book 7. I doubt she would have named the last book
Harry Potter's Survivors and the Triumph of the Dark Lord. But this part of the story is worth noting:
She encouraged the fans to try to piece together future plots for themselves, and urged them to focus on why Harry’s nemesis, the evil warlock Voldemort, had not been killed.
“There are two questions I don’t think I’ve ever been asked and that I should have been asked, if you know what I mean,” Rowling said.
She told the gathering they should be asking themselves “not ‘why did Harry live’ but ‘why didn’t Voldemort die?”’
The second question they should think about is: “Why didn’t Dumbledore kill, or try to kill, Voldemort?” she added, referring to the headmaster of Hogwarts School of Witchcraft and Wizardry.
