When Keanu Reeves announced on Good Morning America in January 2024 that he was co-authoring a novel with China Miéville, the literary establishment did a double take. The man best known for dodging bullets in The Matrix and executing stylised carnage in the John Wick franchise had somehow convinced one of Britain’s most formidable speculative fiction writers – a World Fantasy and Hugo Award laureate who hadn’t published a novel in twelve years – to collaborate on a book set in the universe of Reeves’s comic book series, BRZRKR. The result, The Book of Elsewhere, arrived in July 2024 and promptly became a New York Times bestseller. It is, depending on who you ask, either a “pulpy, adrenaline-fueled thriller” or a meditation on mortality wrapped in ultraviolence. Most likely, it is both.
From Comic Book Boom to Literary Ambition
The origins of The Book of Elsewhere stretch back to 2021, when Reeves made his comic book writing debut with BRZRKR, a twelve-issue series co-created with writer Matt Kindt and illustrator Ron Garney, published by BOOM! Studios. The project was a sensation: a Kickstarter campaign that had targeted $50,000 ultimately raised over $1.4 million, making it the highest-funded comic book campaign on Kickstarter at the time. The series follows B – also known as Unute, Child of Lightning, Death himself – an 80,000-year-old immortal warrior with superhuman strength who works for a U.S. black-ops group in exchange for the truth about his endless, blood-soaked existence.
Reeves had long been captivated by the philosophical dimensions of his character. B is not simply an unkillable action hero; he is a figure grappling with the paradox that immortality, far from being a gift, is a curse. He wants to die – not out of suicidal despair, but because he understands, with the wisdom of millennia, that it is mortality that gives life meaning. It was this tension that compelled Reeves to seek out a literary collaborator who could elevate the material beyond its comic book roots.
“I didn’t want to write the book,” Reeves told The Guardian in July 2024. “I wanted another creator to take that journey. So, ultimately, China has written the novel.” The choice of Miéville was deliberate. Reeves had been a fan of the author’s work since reading his 2015 short-story collection Three Moments of an Explosion. “What struck me was how incredibly well China integrated fantasy and reality,” Reeves explained to The Globe and Mail. “BRZRKR is in that realm.”
Miéville Returns After a Decade Away
For Miéville, the project represented something unusual. The author of Perdido Street Station, The City & The City, and Embassytown – novels that dominated the science fiction landscape throughout the 2000s and earned him the Guggenheim Fellowship for Fiction – had not published a full-length novel since Embassytown in 2011. He had released novellas, including The Last Days of New Paris in 2016, and nonfiction works on international law and Russian revolutionary history, but the novel-length fiction had gone quiet.
When BOOM! Studios asked Reeves who his “dream” author would be to write the book, he named Miéville without hesitation. Reeves admitted he was initially afraid Miéville would decline. “He was a big deal in his circle,” Reeves said. But Miéville was intrigued. As he told The Globe and Mail, the invitation was, in effect, an opportunity “to play with Reeves’s toys” – and the actor’s generosity with his own creations proved a revelation.
The collaboration unfolded over Zoom. Miéville insisted that the project remain secret until both parties were satisfied with the final product, a condition that held through a lengthy creative process. Reeves contributed the initial concept and narrative outline, stipulating only that the story centre on B and his journey to reconcile his immortality. Beyond that, Miéville had considerable freedom.
“It wouldn’t exist in the form without a lot of very thoughtful and careful work with [Reeves],” Miéville later told interviewers. The author, who describes his own genre as “weird fiction” rather than science fiction or fantasy, found that the book allowed him to play in different territory – closer to the sword-and-sorcery tradition of Conan the Barbarian and Michael Moorcock’s Eternal Champion cycles than to the dense urban surrealism of his earlier work.
A Novel That Refuses to Be Just One Thing
The Book of Elsewhere is set in an alternate universe to the main BRZRKR comic continuity, a distinction Reeves and Miéville were careful to establish from the outset. “We’re doing a version of what’s in the comic. We’re not doing a tie-in to the comic, so to speak,” Miéville explained in a 2024 interview with ABC News. The novel revisits and expands the mythology, filling in B’s backstory across tens of thousands of years while maintaining the core tension: the warrior’s yearning for mortality.
The narrative shifts between multiple timelines and perspectives. In the present day, B carries out covert operations for the U.S. military and submits to scientific experiments in exchange for information about his nature. In 1939, a chapter narrated by Sigmund Freud contemplates the nature of consciousness and the self. Across millennia, B encounters gods, monsters, and a baribusa – a boar-like creature with an aeons-long grudge against him – that serves as a mirror to his own impossible existence.
Kirkus Reviews called it “a well-written if elusive treat for fans of modern mythologizing,” while The New York Times described it as “a pulpy, adrenaline-fueled thriller, but it’s also a moody, experimental novel about mortality, the slippery nature of time, and what it means to be human.” William Gibson, author of Neuromancer, offered perhaps the most emphatic endorsement: “An exceptionally innovative collaboration from two remarkable minds.” In the UK, the Daily Mail called it “a gripping, hugely intelligent and beautifully-realised nightmare,” and Stephen Fry declared it “unlike anything else. Boom!”
Not all critics were equally enthralled. Adam Roberts, reviewing for The Guardian, noted that “Miéville’s supple, inventive imagination gets stretched thin on the rack of Reeves’s original idea,” characterising the book as “pulpy hijinks” rather than a work that would stand among Miéville’s masterpieces. The Spectator praised the prose’s “stippled” vocabulary – words like haruspex, khesheph, lingchi, and thowless – while acknowledging the narrative’s looseness. ArtReview pointed to “more than a hint of the sense that this is more about Reeves than anything else: the actor comfortably typecast forever.”
The divided critical response is, in some ways, the most honest indicator that the novel is doing something genuinely unusual. It occupies a strange middle ground between literary fiction and franchise expansion, between philosophical meditation and splatterpunk action. This is precisely the territory Miéville has spent his career mapping, albeit from a different angle.
The BRZRKR Universe Expands
The Book of Elsewhere is not an isolated event. It is one node in an expanding multimedia franchise that Reeves and BOOM! Studios are building with considerable ambition. In March 2021, Netflix acquired the rights to BRZRKR, announcing plans for both a live-action feature film and an anime series. As of early 2025, Justin Lin – the filmmaker who revitalised the Fast & Furious franchise – has signed on to direct the film, with Mattson Tomlin, writer of The Batman Part II and Terminator Zero, penning the screenplay. Lin told The Hollywood Reporter that Reeves had personally intervened to keep the project alive during a difficult financing period, calling the actor an “angel” of the production.
The anime adaptation, to be produced by Production I.G (the studio behind Ghost in the Shell and Haikyuu!!), was confirmed for two seasons. At San Diego Comic-Con in July 2024, it was announced that Tomlin would serve as showrunner, with development beginning that autumn. Reeves is set to voice B in the anime. The novel, meanwhile, has already proved its commercial viability: it became a New York Times bestseller and was released in paperback in the UK by Penguin in July 2025 at £9.99, ensuring continued reach.
What makes the BRZRKR franchise noteworthy from a publishing perspective is the unusual trajectory of its authorship. Reeves conceived the character and the world, but the novel – the most ambitious expansion of that world – was entrusted entirely to a major literary figure. This is not the typical celebrity-author arrangement, in which a ghostwriter or co-author produces something serviceable but unremarkable. Miéville brought his full linguistic and philosophical arsenal to bear on the material, and the result, for all its unevenness, is a genuine collaboration between a Hollywood star and a serious writer, neither of whom was willing to compromise.
Celebrity Novels and the Question of Legitimacy
As our earlier analysis of the rise of celebrity authors observed, the market has been flooded with titles by actors, musicians, and social media personalities, many of which are received with a mixture of curiosity and scepticism. Reeves’s novel resists easy categorisation within this trend. It is not a memoir, a children’s picture book, or a wellness guide. It is a 352-page work of speculative fiction that engages seriously with questions of consciousness, violence, and the ethics of immortality.
Miéville’s participation lends the project a credibility that few celebrity collaborations achieve. The author is not merely lending his name; he is the primary creative force behind the prose. As he told The Globe and Mail, the book is “very interested in a playful but serious way in the way Freud approaches humanity. We contain multitudes; we are legion.” This is not the language of a writer phoning it in for a paycheque.
The critical response – mixed but largely positive – suggests that The Book of Elsewhere occupies a genuine, if liminal, space in contemporary fiction, much as previous genre-defying collaborations have tested the boundaries between commercial fiction and literary ambition. It is neither a masterpiece nor a cash-in. It is something rarer: an experiment that takes its own premise seriously, executed by two artists who respected each other enough to disagree, to compromise, and to produce something neither could have made alone. Whether the BRZRKR franchise continues to produce work of this calibre remains an open question. But the first foray – a novel born from a comic book, written over Zoom between Berlin and Los Angeles – has earned the right to be taken seriously on its own terms.
