What We Can Know

INSTANT NEW YORK TIMES BESTSELLER / From the Booker Prize-winning, bestselling author of Atonement and Saturday, a genre-bending novel full of secrets and surprises, and an immersive exploration, across time and history, of what can ever be truly known

2014: At a dinner for close friends and colleagues, renowned poet Francis Blundy honors his wife's birthday by reading aloud a new poem dedicated to her, "A Corona for Vivien." Much wine is drunk as the guests listen, and a delicious meal is consumed. Little does anyone gathered around the candlelit table know that for generations to come, people will speculate about the message of this poem, the only copy of which goes missing, leading to an enduring mystery.

2119: Just over one hundred years in the future, much of the planet has been submerged by rising seas following a catastrophic nuclear accident. Those who survive are haunted by the richness of the world that has been lost. In the waterlogged south of what used to be England, Thomas Metcalfe, a lonely scholar and researcher, longs for the early twenty-first century as he chases the ghost of one poem, "A Corona for Vivien." How wild and full of risk their lives were,  thinks Thomas, as he pores over the archives of that distant period, captivated by the vivid romances, politics, and betrayals of the era. When he stumbles across a clue that may lead to the elusive poem's location, a story is revealed of entangled loves, long-kept secrets, and a brutal crime that destroys his assumptions about people he thought he knew intimately.

What We Can Know is a masterpiece: a fictional tour de force, a love story about both people and the words they leave behind, and a literary detective story that reclaims the present from our sense of looming catastrophe and imagines a future world where all is not quite lost.
