I may have to wait a while

I am worried that with all the excitement about the latest Harry Potter book, someone in the media is going to leak the ending. So I'm avoiding all the press about it as much as I can. In fact, judging by the letters to the editor in yesterday's NY Times, it looks like they may have given away the ending in their book review. What kind of a jerk would do such a thing?

I don't own any of the other books, and I don't want to buy this one just to find out how it ends, so I reserved a copy from the public library. My place in the queue? 450. I guess I'm not in any hurry.
