What We Can Know

Set against the backdrop of a partially submerged Britain in the year 2119, Ian McEwan’s ambitious novel follows Tom Metcalfe, an academic living on the remaining southern islands. Tom spends his days examining the records of the early twenty-first century, a time of peak human liberty. His quiet research takes a dramatic turn when he discovers a clue pointing to a legendary poem read aloud in 2014 and subsequently lost to history, unraveling a deeper narrative of passion and an ancient crime.

McEwan masterfully constructs a dual-timeline narrative that feels both deeply intimate and grand in scope. The novel shines in its rich details of a changed world, contrasting the melancholic beauty of the flooded lowlands with the vibrant, messy freedoms of our own time. By framing our present day as a lost golden age, the book offers a startlingly original perspective on contemporary life, elevated by McEwan’s trademark psychological precision and elegant prose.

This book is a perfect choice for readers of high-concept literary fiction, speculative mysteries, and thought-provoking drama. It will deeply resonate with anyone who appreciates stories about the preservation of art, the weight of history, and the quiet resilience of the human spirit in the face of monumental change.
