Keanu Reeves is diving further into the literary world.

Reeves, 59, shared a special announcement with Good Morning America on Wednesday announcing that he is collaborating with author China Miéville on a novel titled The Book of Elsewhere, expected to publish in July.

The novel is inspired by BRZRKR, a comic book series the John Wick star first released in 2021, which he co-wrote with Matt Kindt and artist Ron Garney.

“Hi, greetings. I’m very excited for the opportunity to announce that I’ve partnered with one of my favorite authors, China Miéville, on the novel The Book of Elsewhere,” Reeves shared with GMA in a video announcement.

“The series tells the story of an immortal warrior’s fight through the ages, and I love the world of BRZRKR so much that I wanted to explore it further and I thought one of the best ways to do that is through a novel.”

“The Book of Elsewhere will publish in July 2024; if you read it, I hope you love it,” Reeves added. “Thank you.

In a press release shared with PEOPLE, Reeves said that author Miéville “came in with a clear architecture for the story and how he wanted to play with the world of BRZRKR, a world that I love so much.”

“I was thrilled with his vision and feel honored to be a part of this collaborative process,” he added.

Miéville is a New York Times-bestselling author, the recipient of numerous awards and author of more than a dozen novels and non-fiction works, per his official website.

“Sometimes the greatest games are those you play with other people’s toys,” he said in the release. “It was an honor, a shock and a delight when Keanu invited me to play.

But I could never have predicted how generous he’d be with toys he’s spent so long creating, how glad to experiment together, how open to true collaboration.”

The upcoming novel marks another new medium Reeves’ BRZRKR series will take on beyond its initial run as a comic book.

Netflix previously announced in March 2021 that it is adapting the comic book into a feature film starring Reeves that will be followed by a spinoff anime series.

At the time, Netflix’s synopsis for the project described it as “a brutally epic saga about an immortal warrior’s 80,000 year fight through the ages.”

“The man known only as ‘B’ is half-mortal and half-god, cursed and compelled to violence… even at the sacrifice of his sanity,” the synopsis reads.

“But after wandering the earth for centuries, B may have finally found a refuge – working for the U.S. government to fight the battles too violent and too dangerous for anyone else. In exchange, B will be granted the one thing he desires – the truth about his endless blood-soaked existence…and how to end it.”

The Book of Elsewhere is expected to publish in July.
