J.K. Rowling released a new story that has Massachusetts' Harry Potter fans feeling happier than a kid with an invisibility cloak inside Honeydukes.

(That's pretty darn happy, for those of you muggles who have no idea what I'm talking about.)

That's because the latest owl from Rowling tells us that the wizarding world is expanding to the Bay State.

The beloved author revealed Tuesday on her website, Pottermore, a whole new school of witchcraft and wizardry hidden on the peak of Mount Greylock in the Berkshires.

The second installment in a collection called "Magic in North America" is about a secret wizarding school founded in the 17th century called Ilvermorny.

The tale tells the story of an orphaned Irish girl who sails to Massachusetts on the Mayflower, later starting the school for young witches and wizards.

And get excited, nerds, cause you can be sorted into one of Ilvermorny's four houses, too.

On her site, Rowling says the story of Ilvermorny gives readers the history of magic in the U.S. ahead of the release of her upcoming film, "Fantastic Beasts and Where to Find Them," on Nov. 18.
