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)

I always forget how much I enjoy Ian McEwan until I escape into another of his books. The first half is riveting, and I found his depiction of the future and the details of the major events that unfolded absolutely fascinating. The second half is also engaging, but there are some haunting moments that I wish I could forget. There is a satisfying denouement and it was a great listen.

Our literary giants don't often manage to pull off good sci-fi but in the first half of the book McEwan does just that. It's original, the world building works well and of course its well written. Then comes the second half which is set in the present and is OK if you want another tale of middle class literary life. I didn't.

The male reader was more difficult Tom listen to than the female and I had to repeat some parts.

Really interesting view of our future world with a mystery half hidden

worth it

An amazing story within a story, a mouse trap that leads you into an unexpected crime. Brilliant detain and perception of characters and their views, inner lives and loves.
