In a world submerged by rising seas, can the secrets of the past be discovered? The breathtaking Sunday Times bestseller.

2014: A great poem is read aloud and never heard again. For generations, people speculate about its message.

2119: With the UK’s lowlands submerged by rising seas, those who survive are haunted by all that has been lost.

Tom Metcalfe, a university scholar, pores over the archives of the early twenty-first century. When he stumbles across a clue that may lead to the lost poem, he reveals a story of entangled love and a brutal crime that challenges everything he thought he knew about the past.

Critic reviews

What We Can Know may well have created a new genre: the postapocalyptic campus novel. Imagine AS Byatt’s Possession crossed with Cormac McCarthy’s The Road. Dark academia meets the big ideas novel, all conveyed in McEwan’s trim, beautifully ordered sentences (Johanna Thomas-Corr)
An ambitious and an accomplished work of fiction, it’s…rewarding and thought-provoking
What We Can Know is a daring, beautiful novel, full of wisdom and heart (Elif Shafak)
[A] dazzling novel… [What We Can Know] has an eloquent fury about the way our misguided present is allowing nature to shrivel by “slow roasting”
McEwan’s arrestingly relevant new novel… [is] a fiercely involving biblio-mystery deepened by musings on knowledge and understanding, time and memory
A gripping page-turner about marital duty and guilt
An enjoyable work… McEwan excels at exploiting narrative details for dramatic effect
What We Can Know is an astonishing consideration of how the tendrils of the past leak into the present… It’s terrifyingly believable… McEwan cleverly structures the book to reveal his inner workings, while the thoughts he raises around loss…rumble spectacularly throughout
What We Can Know delivers one of McEwan’s finest comic set pieces… [and] can be read as an optimist’s manifesto, a rage against our consensus of decline… [and] a cautionary tale of unchecked nostalgia
An elegy from our future, haunting, playful and ultimately hopeful, What We Can Know is a wonderful book that interrogates the limits of knowledge and interpretation, and bold depiction of our decadent, dying era (Kaliane Bradley)

Enthralling from the start. Really enjoyed this, and it was way more that I expected. Will certainly listen to more of Mr McEwan’s books

Fantastic

I must admit I thought this was rambling rubbish at first but I grew into it.
I’m not a fan of pushing greenhouse gasses ideologies but I’ll forgive it that.
Overall was a good listen, the narrator is brilliant as always with this chap.
Preferred some of Ian’s other books like “Nutshell” brilliant that.
But worth a buy

The narrator is very good as ever.

I personally love the lyrical nature of the prose, and it’s a compelling story. Highly recommended.

Mesmerising

I've read a number of this authors books, wbich I've generally enjoyed. I couldn't engage with the characters and found it implausible that some long lost epic poem should arouse such passion. Did like the future portrayal of a climate changed world. Wish that aspect had been explored in more depth.

Pointless hunt for long lost poem.

Ian McEwan writes such imaginative, scholarly books but he always has an exciting underlying plot and this is no exception. I really enjoyed this, even though I did guess some of the secrets before they were revealed. Great narration too.

Imaginative and compelling
