NEW YORK — Harry Potter is still king, but the final book of Stephenie Meyer's "Twilight" series did manage a million-selling debut.

"Breaking Dawn," the fourth of Meyer's sensational teen vampire series, sold 1.3 million copies in the first 24 hours after its midnight, Aug. 2 release. Publisher Little, Brown Books for Young Readers announced Monday that it has gone back for 500,000 more copies, making the total print run 3.7 million.

The numbers for "Breaking Dawn" are comparable to the openings of a pair of famous memoirs: former President Clinton's "My Life" and Sen. Hillary Rodham Clinton's "Living History." But they don't approach the unveiling of "Harry Potter and the Deathly Hallows." The seventh and final volume of J.K. Rowling's fantasy series sold 8.3 million copies in its first 24 hours in the United States alone.
