“The book’s depth is utterly absorbing, its stories as real in their effect as they are illusory…a huge achievement”

Alexandra Clark
The Guardian


“spectacular…a modern-day Gatsby story and one of the first truly successful fictional reckonings with the financial crisis, as well as a subtle analysis of the British immigrant experience in the current fraught international climate”

Olivia Cole


“[An] astonishing debut…its 497 pages are an intellectual banquet. The ingredients range from philosophy, religion and mathematics to international aid, high finance and carpentry. But the question at its heart is simple: how does knowledge relate to wisdom, happiness and truth? And the story, which ranges from Islamabad to Wall Street and from 9/11 to 2008, is gripping.”

Maggie Fergusson
Intelligent Life/The Economist


“[a] brilliant novel…I was surprised it didn’t explode in my hands.”

Amitava Kumar
The New York Times Book Review


“A great novel…reminded me of Conrad…the contemplative weave of politics and fiction. This ambitious first novel seems to pack into it everything the author knows…and yet it is never show-offy. The characters’ complicated lives, which are at the foreground of the book, persuasively justify everything.”

Wendy Lesser
The Atlantic


“Dazzling in its sweep and depth, Rahman’s debut novel moves seamlessly from Kabul to Oxford to New York to Islamabad. Its Bangladesh-born author — an investment banker turned human rights lawyer — deftly captures the contemporary realities of each setting. Topics touched upon include the global economic collapse, terrorism, exile and immigration, inequality and class, and knowledge as both a political tool and a means of belonging. A magnificent literary feat — and a wholly rewarding read.”

“Brilliant and heartbreaking, In the Light of What We Know is the first truly great book of the new century.”

Ceridwen Dovey
author of Blood Kin


“A stunningly good novel. A pure joy. Lucid, funny, philosophical, and very, very smart … and, I have to tell you, it’s one of my all-time top reads.”

Michael Cathcart
Books and Arts, ABC Radio National


“Rahman’s intellectual range is dazzling. His novelistic intelligence is assured…A page-turning literary novel that tackles the big questions of our present crisis unashamedly, with supreme narrative skill. This, as Henry James might say, is the right real thing…In the Light of What We Know is an indispensable book, almost certainly, in fact, a masterpiece.”

Kevin Power
Sunday Business Post, Ireland


“Deeply insightful and limitlessly quotable, this is the kind of book every novelist dreams of writing and no first-timer should ever have had the chutzpah to attempt. As Rahman’s own narrator says: ‘nothing in his account was out of place, nothing extraneous.’”

A S H Smyth
The Literary Review


“the finest book written by an Indian subcontinent-origin author”…“a stunning piece of literature”

Sandipan Deb
Wall Street Journal India/Mint


“I was captivated by In the Light of What We Know, which I’ve been urging on friends since reading it last summer. A novel that is concerned with friendship, geopolitics, math, and science, it’s talky and intellectual, while also unfolding a riveting drama: a deeply satisfying book.”

“Remarkable…a 21st century novel written with the ambition of scope of a 19th century novel, and bearing the seriousness of purpose of a 20th century one.”

“una de las grandes novelas de nuestro tiempo”

El Correo Gallego, Spain


“I can open this book to any page and find a passage that I want to read aloud to the person next to me. It’s about mathematics, and war, and finance, and relationships, and everything else in the world.”

Ari Shapiro
The New York Times


“[O]n almost every page there was a passage that intrigued me, and made me think something I hadn’t thought before…Is it ‘the first truly great book of the new century’, as one reader claims on the cover? Well, I can’t think of much competition.”

“[an] extraordinary novel”

Ihsan Taylor
The New York Times


“…quite possibly the best South Asian novel of the last 10 years…If there’s one novel that you should read from 2014, it’s In the Light of What We Know. Prepare to be floored by its vertigo-inducing magnificence.”

J Jagannath
Business Standard


“a novel of rare beauty and power…a hugely ambitious work, which could so easily have gone wrong, but Rahman’s towering imagination, combined with his elegant, almost mathematically precise prose, help him pull it off with enviable ease.”

Anvar Alikhan
Outlook, India


“This formidable and compelling novel offers the reader pleasures not often found in the same venue. Its boldness in engaging elements of our contemporary crisis is bracing. In presenting his cast of characters, Rahman supplies close readings of class, mores, and manners that are extraordinary. And throughout, he sustains an almost subliminal resonance with the conventions, strengths, and tone of certain classic social novels in the English canon—Conrad’s in particular. This is a debut to celebrate.”

Norman Rush

“a semantic and linguistic Wonderland”

Nadya Chishty-Mujahid
Dawn, Pakistan


“[The author] sketches astoundingly lucid pictures of several worlds and many lives. In the Light of What We Know is nothing short of a modern classic and Zia Haider Rahman is the kind of raconteur we all have been waiting for.”

Anees Salim
author of Vanity Bagh


“extraordinary…It is no surprise that Rahman’s book is earning rave reviews, gathering much acclaim as it sweeps readers off their feet with its scope and sensibility…It is far away from the colonial narrative of Afghanistan, which makes it a committed political novel if ever there was one.”

Kaveree Bamzai
India Today


“Here it is, the vast and brilliant debut novel of our time for which readers have been waiting…[It is] deeply penetrating and profoundly intimate, as if made by a muralist whose heart belongs to the details. In the Light of What We Know is a novel of startling vision…Who’s the true heir to such greats as George Orwell and V.S. Naipaul? It’s Zia Haider Rahman.”

Richard McCann
author of Mother of Sorrows


“a ground-breaking work of staggering genius…its capacity to accommodate ideas and arguments matches the best of the big, boisterous Russian novels, without its emotional excesses. It restores, with a confidence rarely seen in a first novelist, the majesty of an art form that best tells the history of man.”

S Prasannarajan
Open Magazine, India


“[A] sweeping and brilliant tale…Rahman’s rich and complex debut novel is like [a] great meal…In the Light of What We Know may be the best meal you eat this year. [Rahman’s] insights—whether related to Pakistan-India enmity, Ivy-League attitude or non-governmental organizations’ idealism—were right on target, [his] characters’ experiences plausible and compelling, and [his] grasp of the widely varied subjects in the novel was breathtaking.”

Paul Overby
Pittsburg Post-Gazette


“[A] splendidly enterprising debut…highlights the uncertainty and incoherence uniting a world in which, at a moment, markets can crash and occupied countries can plummet into chaos…a trenchant attempt to represent the scope of all that remains unknown and uncontrollable”

Sam Sacks

“a quiet, philosophical novel of ideas, a meditation on memory, friendship and trust…Beautifully written”

Kirkus Review, Starred


“War can divide friends. But then again, so can peace and all that falls between, the spaces inhabited by this ambitious, elegiac debut novel…”

Huffington Post
Books to Sweep You Off Your Feet 2014


“a dizzying voyage that touches on many of the key issues of our time…an extraordinary achievement…the book overflows with sparkling essays on free will, the perception of time, the nature of memory, maps, flags, etymology and the axioms of mathematics…As a meditation on the penalties of exile, the need for roots and the ways in which anger can consume a thoughtful man slighted by prejudice, this is a dazzling debut.”

David Grylls
Sunday Times


“The author’s fascination with…the universe of ideas is contagious, and enriches the complex narrative about how we know the reality around us…[T]his ambitious debut novel has considerable depth and scope.”

Library Journal Starred Review


“…a literary masterpiece…a magisterial sweep of the landscape of the 21st century that is characterised by war, migration, and rootlessness.”

Lamia Karim
New Age, Bangladesh


“This is not a book that romanticizes brokenness, or creates magic out of trauma, or attempts redemption. Rather, it is a book that looks life in the face, not for what we wish it to be, but for what it is, with all its unkempt truths, its unjustifiable decisions, and things left unsaid, unexplained, uncorrected.”

Sadia Khatri

“This formidable novel unpacks friendship, betrayal, unknowability – and includes an astute take on Englishness, on class, on mathematical theory, human rights, and whether people can trust their own perception of the world.”

Kate Kellaway
The Observer, UK


“Both sophisticated and tender, In the Light of What We Know is an intricate account of the audacity of world-making and a eulogy to our steadfast desire to understand and be understood.”

Lucy Van
Readings, Australia


“Rahman’s book is a mighty tome extending to nearly 500 pages, and dealing with loss and rediscovery and the limits of our experience and understanding of love, relationships, science and war. His writing is powerful and passionate and the full scope of his ideas takes us on a great journey of discovery.”

Tony Woodcock
Huffington Post


“I had steadfastly decided not to be wowed by the praise and approach it with an open mind, but on closing the book, have found my mind open with wonder, and enriched, stimulated and altogether inspired.”

Sajid H. Amit
Dhaka Tribune, Bangladesh


“Niet voor niets komt de Onvolledigheidsstelling van de wiskundige Kurt Gödel al vrij vroeg in het boek aan de orde. De stelling lijkt voor Zafar op veel meer dan alleen zijn wiskundige belangstelling invloed gehad te hebben. Met het verhaal van zijn ooit zo trouwe vriend Zafar neemt de naamloze verteller in In het licht van wat wij weten van Zia Haider Rahman de lezer mee naar vele uithoeken van de wereld. Een boek om helemaal in onder te duiken, waarin de persoonlijke verhouding tussen de twee én de complete wereldpolitiek van deze eeuw voorbij komen. Een boek dat in elke boekenkast thuishoort!”

“…l’ambition et l’intelligence de Rahman montrent déjà la naissance d’un grand talent, assorti d’une haute idée de la littérature.”

Baptiste Liger
L’Express / Lire 


“Dans l’accumulation des histoires et des savoirs, se dessine une carte riche et délibérément lacunaire de notre monde, de notre présent : ce temps d’après – après la crise des subprimes, post-post-11-Septembre, ce temps d’avant –, quand tout est pris dans une confusion inquiète, pas encore éclairé par l’effroi d’un attentat en Afghanistan ou ailleurs … Ce qui subsiste du roman, c’est cette joie réconfortante de l’accumulation de microrécits, de savoirs, comme autant de places fortes qui dessinent en creux un autre pont, celui des « vies inconfortables », sur la frontière … Au vu de ce qui nous attend, À la lumière de ce que nous savons se tient aux avant-postes de la littérature mondiale à venir.”

Lise Wajeman


“Un roman qui interroge la perception que nous avons des autres et de nous-mêmes, et qui met superbement en éveil notre soif de compréhension du monde.”

Charléne Busalli
Page, Les Livres Par Les Libraires


“Transformant sa singulière expérience en récit d’un homme qui a consacré son existence à se dissimuler, l’écrivain n’a pas le romantisme de Gatsby mais la lucide connaissance des classes supérieures de Fitzgerald. Son amertume nourrit un brillant réquisitoire romanesque sur l’impuissance des élites à accueillir la singularité d’un Haider Rahman.”

Oriane Jeancourt Galignani


“Une brillante évocation des enjeux de notre société contemporaine…La littérature, l’Histoire et les mathématiques se rencontrent, et font d’À la lumière de ce que nous savons une somme tout à la fois épique, anthropologique et savante.”

Camille Cloarec
Matricule des Anges


“La dernière page tournée, le lecteur n’a qu’une certitude : il vient de découvrir un écrivain majeur (et ce n’est que son premier roman !), et, malgré le plaisir extraordinaire pris tout au long de sa lecture, malgré son extrême limpidité, une très grande partie de ce roman lui a sans doute échappé, tant il est foisonnant et riche. Mais quel bonheur que de se dire qu’on le relira, encore et encore et qu’il sera chaque fois plus fort, chaque fois plus complexe, À la lumière de ce que nous savons ou pensons savoir.”

Christine Marcandier


“Dense et exigeant, aussi épique que cérébral, son roman force l’admiration par son ambition.”

“His words, in sudden appearance or touch, have an exploratory power and accuracy combined with an illuminating fluidity.”

Liberté Hebdo (Freedom Weekly)


“La barre est haut placée, mais l’intelligence et le talent de Zia Haider Rahman sont à la mesure de ses prétentions, et A la lumière de ce que nous savons est bel et bien un roman—le premier de son auteur—spectaculairement hors du commun, au formidable dessein…Auscultant l’intimité de l’indi­vidu autant que les phénomènes collectifs, rivé aux pensées hautement digressives de l’éloquent et tourmenté Zafar, esprit tout ensemble spéculatif, sensible, caustique et mélancolique, A la lumière de ce que nous savons, en dépit de quelques inévitables longueurs, possède le magnétisme des oeuvres majeures.”

Nathalie Crom


“Coup de coeur de l’année pour le formidable et ambitieux A la lumière de ce que nous savons”

Guillaume Launay


“Roman épistémologique à plus d’un titre, puisqu’il explore les systèmes sociaux, économiques, scientifiques, géopolitiques, littéraires, À la lumière de ce que nous savons est une magnifique ouverture au monde, aux théories, aux sciences. Imposante œuvre littéraire, ce premier roman, intelligent et sensible mais aussi émouvant et captivant est assurément une grande réussite.
Tourner la première page du roman de Zia Haider Rahman c’est plonger au cœur d’un texte brillant, ambitieux, éclairant et qu’on quitte grandi, enrichi, quelque part changé. C’est une œuvre qui nous pousse à affiner notre regard sur le monde, à observer plus intensément, en veillant à appréhender les évènements sous un autre angle mais surtout à comprendre comment nous regardons”

Un Dernier Livre


“Explorant les destins parallèles de deux amis dans la quarantaine, le roman est aussi un véritable festin pour l’intelligence. Un livre foisonnant et stimulant qui cherche d’un bout à l’autre à nouer ensemble des savoirs et des codes disparates pour « élaborer une vision du monde plurielle et complexe ». Des débuts littéraires impressionnants…”

Christian Desmeules
Le Devoir, Canada


À Luz do que Sabemos é o retrato do mundo pós-11/9 nas suas formas mais evidentes: Iluminismo do sector financeiro, terrorismo, povos expatriados. A imagem de Gödel e Einstein a caminharem no terreno de uma quinta americana é um exemplo do desenraizamento que o livro explora em todos os matizes. De Zafar, o protagonista, Rahman poderá dizer o que Flaubert disse da Bovary.”

Eduardo Pitta
Revista Sábado, Portugal


A la luz de lo que sabemos es novela que se desparrama, crece por los bordes, reescribe sus esquinas, arranca y da marcha atrás. El estilo es serio, cuidado, sin afectaciones. Una ambiciosa primera novela de tipo filosófico y de denuncia social, pero a ratos thriller de las corruptelas de guerra y las financieras, que se presta a leer lápiz en mano, pues su extraño ritmo, entre la velocidad de los diálogos y las más pausadas reflexiones sobre temas diversos, nos induce a un estado intermedio entre la meditación, la intriga y el conocimiento.”

Verónica Nieto
Revista de Letras, Spain


“Man fühlt sich durchaus in einem Zauberberg, wenn dieser Romanheld mit der eigenen Geschichte erzählt, wie fundamentale Triebkräfte zwischen Liebeswunsch und Rachsucht im Dschungel von postmodern globalisiertem Leben, Wissen und Denken ihren Weg finden und womöglich explodieren.”
