“Downton Abbey” is coming to an end, but Julian Fellowes isn’t done writing. The showrunner will release a book, “Belgravia,” and he’ll stick to historical fiction. But the manner of the release will blend Victorian and 21st century traditions.

“Belgravia” will first be released digitally, and readers will receive each chapter on a weekly basis. The app will launch in June via the book’s official website. Fans can buy each installment individually or subscribe to get them all. The serial release echoes how many books were published in the Victorian era, which is the period Fellowes will be writing about.

The novel, released by Grand Central Publishing, will follow a large cast of characters, some of whom come from new money while others have been born into the aristocracy. “Set in the 1840s when the upper echelons of society began to rub shoulders with the emerging industrial nouveau riche, 'Belgravia' is peopled by a rich cast of characters,” the official description reads. “But the story begins on the eve of the Battle of Waterloo in 1815. At the Duchess of Richmond’s now legendary ball, one family’s life will change forever…”

Entertainment Weekly reports that fans will be able to see bonus features, “including character portraits and period fashions,” through the app. Each chapter will also be available as an audio book.

“Belgravia” isn’t Fellowes’ only writing project. He is scheduled to write a TV adaptation of Anthony Trollope’s “Doctor Thorne,” a real Victorian novel, Deadline reports. He also recently said he is working on a script for a “Downton Abbey” movie.

“So much of this depends on the script. For me, it’s the real key here,” he told Vulture in November. “This holds a great deal of interest for me, because I still have more to say with ‘Downton.’ I see this transitioning to film quite well, and I certainly am the person to tell this story.”

The film version still hasn’t officially been ordered, though.

“Belgravia” will start being released digitally in April, and a print version will hit shelves in June.
