The Internet retailer says United States fans have ordered more than 620,000 copies, with more than 250,000 orders coming from the United Kingdom.

Fellow bookseller Barnes & Noble said in April that pre-orders for the book surpassed 500,000 copies, breaking the chain's record for advance requests.
