I've never read a Harry Potter book so I don't have any way to judge for certain the authenticity of what I just read over at one of those bit torrent sites, but it does appear that the new Harry Potter book is out on the web and has been accessed by thousands of people already. It appears that someone has photocopied the entire thing, two pages at a time, and has made it available for illegal downloading. The site that had it up originally has taken it down but it was too late to keep it from spreading to other sites that specialize in that kind of thing.
I was able to read a chapter-by-chapter summary of the book and look at a few sample pages, some with pictures, without having to illegally download a thing.
I'll never understand what people get out of spoiling something for so many people. I post this here as a warning to those who might spot these links somewhere and be tempted to look at them. They look like the real thing to me. If you don't want to have the whole experience ruined for you, stay away from these sites.
