Fans of Harry Potter had a special treat this week: a new installment from author J.K. Rowling on the boy wizard.  

The 1,500-word story was published on her website, Pottermore.com, Tuesday morning.  It’s the most complete update of the boy wizard since the last book of the series “Harry Potter and the Deathly Hallows,” came out in 2007.  

There are some interesting new details about Harry and his close friends, Ron Weasley and Hermione Granger, who are in their 30s in this new story.

For many fans who grew up with the beloved characters, the update was a welcomed surprise, says Alison Siggard, who first began reading the Harry Potter series at the age of five.

"It's exciting that we're seeing them in adult life as we're getting into adult life, as well," said Siggard, now 20. Siggard is currently a writer for the site, mugglenet.com.
