She may not have magic powers, but Katniss Everdeen has a leg up on Harry Potter.

Suzanne Collins' "Hunger Games" series has surpassed "Harry Potter" to become the best-selling book series on Amazon.com, the retail giant announced Friday.

No actual sales figures are available at this time, but Amazon said "Games" is now the most popular book series in the site's history.

"Interestingly, this series is only three books versus Harry Potter's seven, and to achieve this result in just four years is a great testament to both the popularity of the work and, we think, the growth in reading digitally during that time," said Sara Nelson, the editorial director of book and Kindle at Amazon.

"The Hunger Games" has also become the most-borrowed e-book in Amazon's Kindle library, though that statistic may be less impressive considering the "Potter" series was not available in e-book format until March of this year.

Scholastic, which published both "Potter" and "Games," announced in July that more than 50 million copies of Collins' trilogy are available in both print and digital formats. All seven "Harry Potter" books have sold a combined 450 million copies worldwide.

This isn't the first J.K. Rowling record to be broken lately.

Amazon also announced last week that the "Harry Potter" author had been replaced by "Fifty Shades of Grey" scribe E.L. James as the best-selling author in history on Amazon's British site, Amazon.co.uk.
