The new York Times has a review of the final Harry Potter novel already printed and it gave away many spoilers. Take a look here if you want to see.
Scholastic has recently learned that some individuals have received copies of Harry Potter and the Deathly Hallows through the mail , beginning on Tuesday, July 17th, as a result of a breach of the on-sale agreement by the distributor, Levy Home Entertainment, and shipments made by DeepDiscount.com, a customer of that distributor. We are taking immediate legal action against DeepDiscount.com and Levy Home Entertainment. The number of copies shipped is around one one-hundredth of one percent of the total U.S. copies to go on sale at 12:01 am on July 21st.
