Extremity

From H.G. Wells’ The Time Machine (1895) to Octavia E. Butler’s Kindred (1979) and Arthur C. Clarke and Stephen Baxter’s A Time Odyssey Trilogy (2003-2007), writers have probed temporalities to question the nature of existence, our relation to history, and the limits of ethics in relation to technology. Extremity, a 2025 novella by Nicholas Binge, fuses the UK police procedural with the time travel subgenre to concoct a brisk, action-driven work about murder, a nightmarish future, and a mysterious time machine.

Binge’s 2023 breakout Ascension garnered raves from critics and the public. The novel concerns the sudden appearance of a mountain the size of Everest in the middle of the Pacific Ocean and an expedition that explores the mammoth structure. Ascension was selected as a New York Times ‘Editor’s Choice Pick’ with many noting its successful blending of action, suspense, and Lovecraftian elements. Binge’s Dissolution (2025) focuses on a man whose Alzheimer’s may be concealing the erasure of his memory by an external force. Extremity joins multiple novellas published annually by Tordotcom. The Tor Publishing Group imprint remains dedicated to the (re)-emerging novella market.

Constructed from three interwoven testimonies of investigators, Extremity’s action begins with the murder of billionaire tech giant Bruno Donaldson in contemporary London. Across the city, far from Donaldson’s penthouse, an exact replica of Donaldson—also dead—is located under a graffiti scrawled bridge.  This bizarre discovery sets into motion a series of rapidly accumulating dead bodies and strange occurrences across the city. The reader traces much of the narrative through Julia Torgrimsen, a celebrity detective who has drifted into retirement and obscurity. She has been asked to return to determine the cause of these odd events. By her side is rookie DC Mark Cochrane and veteran DCI John Grossman. The investigators follow up with Donaldson’s criminal colleagues, bodies begin to pile up, an assassin is revealed, and the investigators stumble across a series of files that have future stock reports, photographs of body parts, and labels such as “date of attempted breach” and “date of disposal.” Eventually, our protagonists uncover a conspiracy that involves Earth in 6 million years, interaction with an unknown malevolent intelligence, boneless clones, and the ability to travel to the future.

Perhaps the strongest part of Extremity resides in its structure and action-driven writing. Composed of three alternating testimonies from our investigators, the narrative cohesively presents the action to its readers. Unfortunately, the three characters’ voices are interchangeable. With three differing perspectives, I was expecting to witness conflicting perspectives on the events. Yet, very rarely do the investigators provide contradictory testimonies. In a structure that could have yielded narrative complexity, the author employs the structure as a contrivance. In essence, the chosen structure and form minimally serve the content of the work.

Undoubtedly, Extremity possesses a strong hook: two dead bodies, identical in all ways, are discovered. The proceduralism sprints quickly from page to page, providing the reader with little time to catch their breath or to consider the logic of the tale or the ideas at play. And perhaps that is effective, because little of the work holds up to scrutiny regarding character, reason, motivation, or science. Extremity works as an excellent “action film” on the page, but not as science fiction invested in anything beyond an entertaining joyride. The writing itself propels the reader along—yet reflection on the events and characters reveals that the pace conceals many of the work’s faults. Extremity serves as a lightning quick read but is rarely challenging. That is not to say there is not a place for literature as pure entertainment crafted for pleasure and action, but this novella could be enriched by embracing complexities, paradoxes, and unseen concepts to captivate the reader beyond action.

The plot owes a great deal to police procedurals that have remained popular on UK screens and pages for decades. The science fiction elements of the novella truly manifest toward the end of the work. The “science” is cursory at best, yet there are a few time travel dynamics that are compelling, but—as with other elements—they are not sufficiently explored. Though one would expect a novella merging the police procedural and science fiction to locate commonalities with the work of Phillip K. Dick, I see little crossover.

Extremity does not further the subgenre in terms of intellectual concerns. That said, Extremity moves at a whiplash pace and illustrates how to propel action forward. Sadly, this results in implausible plot points, shallow characters, and ideas that would benefit from further contemplation. Unfortunately, characters make choices that seem unaligned with their established personalities, information dumps intrude, leaps of deduction are made, and there stands no real probing of the science and consequences of time travel. Further, police procedural cliches abound, while the lack of credibility in action makes one wish for more heavy editorial interference. There is no question that Binge writes solid action. Now, if he could graft the sophisticated ideas and challenging notions that thrive in science fiction to his writing in Extremity, I believe the result would be fulfilling.

In all, Extremity stands as a fast-paced, action-driven novella that is not invested in exploring the power and paradox of time travel but simply in taking the reader for a thrilling jaunt. The work trades in heady ideas of morality and temporal alterations for pushing the characters through a series of kinetic scenes. Extremity owes less to other noteworthy entries in the time travel subgenre and rests firmly in the tradition of many entertaining pulp tales that provided rip-roaring action but very few notions regarding humanity, time, and the consequences of our actions. Extremity does not further the time travel subgenre in any determinable way, but serves as an inoffensive, at times credibility-straining, piece of escapist literature.
