These books do not ask for reverence. They ask only that you keep reading
Faith is a slippery thing. It’s often inherited before it’s understood—passed down like a name, a flag, or a recipe, only later to be wrestled with in private. And when it falters, it rarely does so all at once. A question creeps in here, a contradiction appears there.
The books in this list may rattle your convictions and demand a reckoning—not just with religion or belief systems, but with the frameworks we use to understand good and evil, suffering and grace, doubt and meaning.
Some do this directly, taking theology and dogma head-on. Others sneak in sideways, confronting the reader with moral ambiguity, unexplained phenomena, or characters whose belief is both their compass and their undoing. Discover more below.

‘Annihilation’ by Jeff VanderMeer

Above ‘Annihilation’ by Jeff VanderMeer
Is it divinity or decay that rewrites the laws of life in Area X?
Area X has been cut off from the rest of the world for decades. Nature has reclaimed the last vestiges of human civilisation. The first expedition returned with reports of a pristine, Edenic landscape; the second ended in mass suicide, the third in a hail of gunfire. By the eleventh, the survivors came home shadows of themselves, dead within weeks from aggressive cancer. The twelfth expedition, composed entirely of women—a psychologist, an anthropologist, a surveyor, and our narrator, a biologist—enters the unknown with clinical detachment.
But “detachment” doesn’t last. As they traverse the terrain and descend into a strange, pulsing tunnel (or is it a tower?), the biologist becomes increasingly untethered—from the mission, from the others, from her own memories. Annihilation is a novel that doesn’t so much question faith as it annihilates the structures that make belief possible: language, science, even the self. And in the ruins, it asks: If you could see life as it truly is—uncaring, unknowable, possibly divine—would you still want to?
‘The Da Vinci Code’ by Dan Brown

When belief becomes a conspiracy, who gets to guard the truth?
While in Paris on business, Harvard symbologist Robert Langdon is called to the Louvre, where the murdered curator’s body has been left with a mysterious cypher. What follows is a trail of riddles hidden in Renaissance art, secret societies, and sacred texts, suggesting that everything we thought we knew about the life of Jesus Christ—and his legacy—has been deliberately concealed.
Dismissed by many as pulp and by others as blasphemy, The Da Vinci Code remains one of the 21st century’s most talked-about novels, precisely because it capitalises on a deeper unease: What if centuries of belief were built not on divine revelation but on institutional power? It’s not theology, but the thrill of theological disruption. Even sceptics may find themselves wondering if there are still secrets hiding in plain sight.
‘Silence’ by Shūsaku Endō

Above ‘Silence’ by Shūsaku Endō
When God is silent, is it abandonment—or a different kind of presence?
Set in 17th-century Japan, where Christianity is outlawed and its followers persecuted, Silence follows Portuguese Jesuit priest Sebastião Rodrigues as he travels to locate his mentor, who is rumoured to have apostatised. What he finds is a land soaked in fear and sacrifice, where converts are tortured unless their priests renounce the faith.
The novel’s great question is not whether suffering exists, but whether a just God can remain silent in its presence. Endō, a Catholic in a largely Buddhist country, writes not to vindicate belief but to strip it down to its barest, most agonising form. This is a novel for anyone who has ever prayed and heard nothing in return.
‘The Left Hand of Darkness’ by Ursula K. Le Guin

What if belief is not in gods, but in each other?
This sci-fi classic is set on the planet Gethen, where humans have no fixed sex and society has evolved without the strict binaries that structure Earth’s cultures and religions. Genly Ai, an emissary from another planet, arrives to convince Gethen’s leaders to join an interstellar alliance—but his assumptions about gender, trust, and meaning are constantly upended.
Though not about religion in the traditional sense, The Left Hand of Darkness forces readers to examine the metaphysical frameworks we inherit. On Gethen, spirituality exists, but it looks nothing like what Genly expects. Le Guin, always interested in anthropology and myth, gently prods: What if faith is not a structure but an attitude—one we adopt toward other people, in their mystery and their wholeness?

‘The Road’ by Cormac McCarthy

Above ‘The Road’ by Cormac McCarthy
In the ashes of the world, a father’s love is the last remaining prayer.
A man and his young son wander through a post-apocalyptic landscape, scavenging to survive, avoiding cannibals and despair. The world has ended, and with it, any external markers of meaning. There is no church, no text, no community. There is only the man’s unwavering insistence that they are “carrying the fire.”
What that fire is—hope? morality? God?—is never made explicit. And that’s precisely the point. The Road is a meditation on the thin, flickering thread of faith in the absence of proof, tradition, or reward. It is brutal and beautiful, and for many, unexpectedly sacred.
‘Life of Pi’ by Yann Martel

Believe the better story.
Shipwrecked in the Pacific Ocean, a teenage boy named Pi Patel survives 227 days on a lifeboat with a Bengal tiger named Richard Parker. When he’s eventually rescued, investigators demand a rational account. Pi offers them two stories: one with the tiger, and one without. “Which is the better story?” he asks. They chose the first.
Life of Pi is not a theological treatise, but a parable about belief itself. The question is not which version is true, but which version makes survival—both physical and spiritual—possible. Sometimes, Martel suggests, we choose faith not because it is provable, but because it keeps us afloat.
‘Gilead’ by Marilynne Robinson

Above ‘Gilead’ by Marilynne Robinson
What if the hardest test of faith is not doubt, but forgiveness?
On the surface, Gilead is a gentle book—an epistolary novel written by an ageing Congregationalist minister, John Ames, to his young son. Set in a quiet Iowa town in the 1950s, it’s composed of reflections on scripture, history, fatherhood, and memory. But beneath its pastoral calm lies a more unsettling current: Gilead is not about unwavering faith, but about faith tested by time, loss, and the limitations of the self.
Marilynne Robinson’s great achievement is making holiness feel both luminous and ordinary. Ames finds grace in sunlight through trees, in a child’s laughter, in the slow passage of time—but he also wonders whether any of it matters. His son will grow up without him. His small-town sermons may not survive the modern age. Gilead doesn’t test faith with catastrophe, but with a subtler question: Can belief endure without vindication—without triumph, certainty, or even audience? It’s a novel of unanswered prayers and small, redemptive gestures. And in its quiet way, it’s one of the most radical books about religion you’re likely to read.
