Ian McEwan’s latest novel, What We Can Know, arrives as perhaps his most philosophically ambitious work yet, weaving together climate catastrophe, academic obsession, and the eternal mysteries of human connection into a narrative that feels both urgently contemporary and timelessly universal. Set in a future where rising seas have transformed Britain into an archipelago, the novel operates on multiple temporal levels, creating a meditation on what we preserve, what we lose, and how memory shapes reality.
The story centers on Tom Metcalfe, a scholar in 2119 researching the “Second Immortal Dinner” of 2014—a literary gathering where poet Francis Blundy read his fifteen-sonnet corona “A Corona for Vivien” to a small group of friends. The poem, never published and subsequently lost, becomes the novel’s absent heart, driving both academic inquiry and personal obsession across a century of speculation and longing.
The Architecture of Absence
McEwan constructs his narrative around a brilliant conceit: the biography of a non-existent poem. The corona exists only in the fragmentary memories of those who heard it, in scholarly speculation, and in the cultural mythology that grows around lost things. This absence becomes paradoxically powerful, allowing McEwan to explore how imagination often proves more potent than reality, how the unreachable object of desire maintains its perfection precisely because it remains untouchable.
The dual timeline structure—moving between the 2014 dinner party and the 2119 research expedition—creates a poignant dialogue between past abundance and future scarcity. McEwan’s vision of a climate-changed Britain feels both plausible and haunting: the Bodleian Library relocated to the peaks of Snowdonia, accessible only by ferry and funicular, while the drowned lowlands serve as ghostly reminders of what has been lost. The author demonstrates his familiar gift for embedding profound themes within meticulously researched, believable worlds.
Love in Multiple Keys
At its core, the novel examines several interlocking love stories, each marked by miscommunication, mistiming, and the gap between desire and fulfillment. The relationship between Francis Blundy and Vivien—the poem’s ostensible subject and recipient—reveals itself as complex and troubled beneath its surface devotion. Blundy’s artistic dedication, particularly his obsession with the dying Percy, creates fissures that his grand romantic gesture cannot repair.
Tom Metcalfe’s relationship with his colleague Rose Church parallels these earlier entanglements, as academic ambition and personal jealousy threaten their partnership. The introduction of the younger Kevin Howard—brilliant, inexperienced, and disastrously romantic—provides both comic relief and genuine pathos, as his naive intensity mirrors the various forms of unrequited longing that permeate the narrative.
McEwan handles these romantic entanglements with characteristic precision, avoiding both cynicism and sentimentality. His characters feel fully human in their contradictions—capable of profound feeling yet prone to spectacular misunderstandings, intellectually sophisticated yet emotionally clumsy.
Climate Fiction with Literary Soul
While What We Can Know functions as climate fiction, McEwan avoids the genre’s typical pitfalls of didacticism or despair. His future Britain, though diminished, retains pockets of culture and learning. The novel suggests that while we may lose much to environmental catastrophe, human creativity and the impulse to preserve knowledge persist. The dedication to maintaining libraries and universities, even in reduced circumstances, speaks to resilience rather than resignation.
The ecological themes emerge naturally from the narrative rather than overwhelming it. The contrast between the rich natural world described in Blundy’s lost poem and the simplified ecosystem of the future archipelago creates emotional weight without heavy-handed messaging. McEwan trusts his readers to draw their own conclusions about loss, preservation, and responsibility.
The Biographer’s Art
McEwan’s exploration of biographical methodology proves particularly sophisticated. Tom Metcalfe’s struggle to animate historical figures from fragmentary evidence mirrors the novelist’s own task of creating convincing characters from imagination. The novel becomes a meditation on the relationship between fact and fiction, questioning what we can truly know about other people’s interior lives and motivations.
The revelation of Vivien’s confessions near the novel’s end—her account of burning the poem—adds layers of complexity to questions of artistic preservation and personal agency. Her decision to destroy the work rather than see it published against her wishes transforms her from passive recipient to active agent in the poem’s fate, challenging assumptions about artistic ownership and the public good.
Technical Mastery and Emotional Resonance
McEwan’s prose remains as controlled and elegant as ever, adapting subtly to different narrative voices and time periods. His rendering of academic life feels authentic without becoming insider baseball, while his depiction of the future world balances scientific plausibility with literary atmosphere. The novel’s structure—moving between research, personal drama, and historical recreation—maintains momentum while allowing space for philosophical reflection.
The handling of the central literary mystery demonstrates particular skill. McEwan manages to make readers care deeply about a poem they never read, investing Blundy’s corona with significance through the passionate responses it generates rather than through direct quotation. This technique reinforces the novel’s themes about the power of the imagined over the actual.
Minor Reservations
While the novel succeeds admirably in most respects, some elements feel occasionally forced. The parallels between past and present relationships sometimes verge on the schematic, and certain plot developments—particularly involving the rivalry over Rose Church—can feel predictable. The novel’s final sections, while emotionally satisfying, rely perhaps too heavily on coincidence and convenient revelations.
Additionally, readers expecting McEwan’s trademark psychological intensity might find What We Can Know more cerebral than visceral. While the characters are well-developed, they sometimes feel like vehicles for ideas rather than fully autonomous beings driven by their own mysterious depths.
A Worthy Addition to an Distinguished Career
What We Can Know stands as a mature work from a writer at the height of his powers, combining the environmental concerns of Solar, the historical sweep of Atonement, and the philosophical depth of The Children Act. McEwan has created a novel that works both as speculative fiction and as literary meditation, offering pleasures for readers seeking either intellectual engagement or emotional satisfaction.
The novel joins conversation with other recent climate fiction while maintaining McEwan’s distinctive voice and preoccupations. Like Margaret Atwood’s MaddAddam trilogy or David Mitchell’s The Bone Clocks, it imagines future consequences of present choices while never losing sight of individual human experience within larger historical forces.

Final Verdict
What We Can Know confirms McEwan’s position as one of our most thoughtful novelists, capable of addressing large themes through intimate human stories. While it may not reach the emotional heights of Atonement or match the satirical bite of Solar, it offers its own distinct pleasures: intellectual sophistication, narrative elegance, and genuine insight into how we create meaning from loss.
The novel succeeds in making the case that literature matters not because it provides answers, but because it asks the right questions about love, memory, preservation, and the stories we tell ourselves about who we are and what we value. In our own age of environmental crisis and cultural fragmentation, these questions feel more urgent than ever.
For readers willing to engage with its philosophical complexities and patient enough to appreciate its measured pace, What We Can Know offers rewards that linger long after the final page. It stands as both entertainment and meditation, confirming that literary fiction at its best can illuminate the present by imagining the future, and help us understand what we might lose—and what we might yet save.
