A Canadian judge has ordered the 14 people who were mistakenly allowed to buy copies of the new Harry Potter book this week not to divulge anything about the story. “The book was sold to 14 people who snagged a copy of J.K. Rowlings’ much anticipated “Harry Potter and the Half-Blood Prince,” when it landed on shelves last Thursday at a local grocery store. The book, officially set for release this coming Saturday, has been shrouded in secrecy and its debut has been highly orchestrated to enable everyone — readers, reviewers, even publishers — to crack it open all at once. It’s the sixth in Rowling’s seven-book fantasy series on the young wizard.”
