Book Review

Title: Nod by Adrian Barnes

Genre: Psychological, Horror, Dystopian

Rating: 3.5 Stars

I’m not entirely sure what I expected when I picked up Nod, but I can confidently say I wasn’t expecting quite this strange reading experience. Part post-apocalyptic horror, part psychological nightmare, part philosophical exploration of language, belief, and human nature, Adrian Barnes has written a book that is difficult to categorise and, at times, even more difficult to understand. It is an undeniably interesting concept, and there are moments of genuinely brilliant writing, but I found myself equally fascinated and frustrated by what Barnes was trying to achieve. There is a lot happening beneath the surface, and while I appreciate the ambition, I’m not entirely convinced every element comes together as successfully as it could have.

---

The premise is wonderfully unsettling. One morning, the world wakes to discover that almost nobody has managed to sleep. A tiny minority, including our narrator Paul, remain capable of sleeping, while the overwhelming majority of humanity are suddenly afflicted with an inexplicable form of insomnia. What initially seems like a temporary inconvenience quickly becomes a global catastrophe. As the days pass, the sleepless begin to experience increasingly severe psychological deterioration, eventually descending into madness and violence. Civilization starts to collapse, and those who can still sleep become an increasingly endangered minority.

It’s a brilliant premise because it takes something so fundamental to human existence and turns its absence into an extinction-level event. Sleep is something most of us take for granted, something we rarely consider beyond its immediate impact on our mood and ability to function. Barnes asks us to imagine what would happen if that essential part of being human suddenly disappeared. The answer is considerably more disturbing than simply having a very unpleasant few nights.

One of the things I particularly enjoyed was the way the deterioration of society is portrayed. Rather than relying entirely on the usual post-apocalyptic tropes of zombies, monsters, or some external force destroying humanity, Barnes explores what happens when the human mind itself becomes the source of the catastrophe. The people around Paul aren’t necessarily evil, nor are they transformed into something entirely different. They are ordinary people gradually losing their ability to think rationally, regulate their emotions, and distinguish reality from their increasingly fractured perceptions. The frightening thing is how little separates the civilization we recognise from the chaos that replaces it. Remove one fundamental biological requirement and the structures we have built our lives around begin to fall apart with astonishing speed.

Paul is an interesting, if not always particularly likeable, protagonist. An etymologist working on a book about forgotten and discarded words, he is naturally inclined to observe the world through language and meaning rather than through emotion. His detached, sometimes almost clinical approach to the unfolding disaster makes for an unusual perspective, although I occasionally found myself wanting more emotional depth from him. His relationship with Tanya, who is among those affected by the insomnia, provides the story with its most personal tragedy. Watching someone you love gradually lose their sense of self is a particularly horrible prospect, and their relationship adds a layer of sadness to what could otherwise have been a rather abstract exercise in apocalyptic horror. There is also Zoe, the mysterious child who becomes part of their lives, whose presence introduces another interesting dimension to the story.

However, I think the most fascinating aspect of Nod is actually its exploration of language, and this is where I believe the book becomes considerably more than a straightforward apocalypse novel. Paul’s work on forgotten words initially seems like an unusual character detail, but it gradually becomes central to the philosophical ideas underpinning the story. Barnes appears interested in the relationship between language and reality: how the words we use shape the way we understand the world, how forgotten words represent forgotten concepts, and whether something can effectively disappear from our collective reality simply because we no longer have the language to recognise or describe it.

I found this particularly interesting when considering the different groups that emerge among the Awakened. As rational thought deteriorates, people begin creating their own explanations for what is happening. Beliefs become increasingly detached from reality, but that doesn’t necessarily make them powerless. In fact, the ability to construct a convincing narrative and persuade others to believe it becomes one of the most powerful tools available. Charles, in particular, demonstrates how easily people can be drawn towards someone who offers an explanation, a purpose, or even just the illusion of order when everything around them has become incomprehensible.

This is where I think Barnes makes one of his strongest observations about human nature. We like to believe that we are rational creatures who form our opinions based on evidence, but how much of that is actually true? When confronted with something we cannot explain, we have an almost instinctive need to create meaning. We would rather believe an extraordinary explanation than accept that we simply don’t know what is happening. In a world where the usual structures of authority, science, and social organisation have collapsed, whoever can provide the most convincing story can potentially become the most powerful person in the room. The apocalypse in Nod isn’t just biological; it is also an epidemic of competing beliefs, stories, and invented realities.

I also think there is an interesting distinction between being awake and being truly aware. The Awakened are physically unable to sleep, but their increasing loss of rationality makes them less capable of understanding the world around them. Meanwhile, the Sleepers, who retain the ability to rest and dream, become outsiders in a society that increasingly views them with suspicion. There is an almost ironic reversal here: those who cannot sleep are technically awake, but they are progressively losing their grasp on reality, while those who can sleep are the ones who retain their ability to think clearly. Perhaps Barnes is suggesting that simply being conscious isn’t the same as being enlightened, and that our understanding of reality depends on considerably more than what we can physically perceive.

The title itself also adds another layer to this interpretation. Nod is traditionally associated with the biblical land to which Cain is exiled after murdering Abel. It is a place of separation, wandering, and alienation. I think this is a particularly fitting title for a novel in which humanity becomes separated not only from sleep but from the shared understanding of reality that makes civilization possible. Everyone is essentially wandering through their own version of Nod, trying to make sense of a world that no longer operates according to the rules they once understood. The idea that humanity has been exiled from something fundamental to its existence feels particularly appropriate.

That said, I did find the book’s more abstract elements occasionally worked against it. There are times when the philosophical ideas become so prominent that the actual narrative seems to lose direction. I appreciated the symbolism and the underlying commentary, but I sometimes wanted Barnes to spend less time presenting interesting concepts and more time allowing them to develop naturally through the characters and events. Paul’s narration can also feel emotionally distant, which makes it harder to connect with some of the more devastating developments. There is a lot to think about, but intellectual interest and emotional investment aren’t always the same thing.

What I found most interesting, however, is the question of what Barnes is ultimately saying about humanity.

My interpretation is that Nod is less concerned with the end of civilization than with exposing how fragile the idea of civilization is. We like to think that society is built upon rationality, shared values, and an established understanding of the world, but perhaps it is held together by something much more precarious: our collective agreement about what is real, what matters, and how we should behave. Take away the ability to sleep, and that agreement begins to disintegrate. People turn to increasingly bizarre beliefs, create their own systems of meaning, and become willing to commit terrible acts in defence of those beliefs.

But I think there is another, perhaps more uncomfortable, interpretation. The world before the insomnia was not necessarily as healthy or rational as we might like to imagine. The catastrophe doesn’t create every human failing from nothing; it magnifies what was already there. The paranoia, tribalism, obsession with power, and willingness to follow charismatic figures all have their roots in recognisable aspects of ordinary human behaviour. In that sense, the apocalypse is less a transformation of humanity than an acceleration of tendencies that were already present.

The forgotten words Paul studies become particularly relevant here. Perhaps the things humanity has lost aren’t simply words, but the ideas and ways of understanding the world that those words once represented. We have become so accustomed to our modern understanding of reality that we rarely question what might exist beyond it. When that understanding collapses, we discover just how little we actually know. I don’t think Barnes necessarily offers a clear answer to what is happening or why, and I suspect that uncertainty is intentional. The mystery is part of the point.

Ultimately, Nod is a strange, ambitious, occasionally frustrating, but undeniably thought-provoking novel. I loved the central premise and the way Barnes uses a seemingly simple biological phenomenon to explore much bigger questions about language, belief, consciousness, and the fragility of human civilization. The writing is often beautiful, the atmosphere is wonderfully bleak, and there are some genuinely disturbing moments. However, I did find the narrative occasionally overwhelmed by its own ideas, and I would have appreciated a little more emotional depth and cohesion.

I don’t think this is necessarily a book that will appeal to everyone, and I can understand why some readers might finish it feeling more confused than enlightened. Even so, I think there is something quite impressive about a novel that leaves you questioning not just what you have read, but what it was actually trying to tell you. I may not have fully unravelled everything Barnes intended, and I’m not sure I agree with every direction the story takes, but I certainly found myself thinking about it long after putting it down.

A fascinating, unsettling exploration of what happens when humanity loses the ability to rest, and perhaps more importantly, the ability to agree on reality. Not quite everything I wanted it to be, but certainly a book worth thinking about.
