Harry Potter author J.K. Rowling will mark the release of the final book in the hugely popular series by giving a midnight reading and signing in London.
About 1,700 lucky fans in Britain and Ireland will win a chance to have Rowling sign a copy of "Harry Potter and the Deathly Hallows." The event will take place at the Natural History Museum on July 21, the day the book is released.
The first 500 randomly selected winners will also be invited to attend the midnight reading. Timed tickets will be issued for the subsequent book signing, which is expected to last until dawn. All the winners will receive a free copy of the book.
Seven U.S. residents can enter to win round-trip tickets to London and hotel accommodations to participate in the reading.
The book is the seventh and final installment about the adventures of the schoolboy wizard; Rowling previously has said that two characters die in the final book.
The Potter books have sold more than 325 million copies worldwide with translations into 64 languages.
