natalie - when ever anything this random pops up in the "literature" section a harry potter fan is not far behind - give them a few hours of googling and they'll all be here soon "BUT WHO IS THE HALF BLOOD PRINCE" - wait for it and then read the book!!!
The answer for anyone else who's interested is 'chapters'. It's the riddle to get through the door into the Room of Requirement on JK Rowling's site - www.jkrowling.com
Is there anything else to see after you answer the riddle? I thought there was a passage from the book and other things.... I also thought there were a lot of puzzles to go through.... Help?
to "Cho Chang", you have to retrieve the magnifiying glass from the drawer, and look at the folder on the desk. It gives you the names of three chapters in the 6th book. Other than that, I don't believe their is anything else to look at.
