What We Can Know - Ian McEwan

"What We Can Know" by Ian McEwan is a brilliantly imagined literary thriller that combines mystery, romance, historical investigation, and speculative fiction into a captivating narrative. Spanning more than a century, the novel moves between the early twenty-first century and a future transformed by climate catastrophe. In 2119, rising sea levels have submerged much of Britain, leaving survivors scattered across a fragmented archipelago. Among them is Tom Metcalfe, a scholar fascinated by the lost world of the past and obsessed with uncovering the truth behind a legendary poem first read aloud in 2014 and never heard again. As Tom follows a trail of clues through forgotten archives, he uncovers a story of love, betrayal, obsession, and murder, forcing him to question everything he believed about history and human nature. Richly intelligent, emotionally engaging, and profoundly relevant, the novel explores the relationship between knowledge, memory, and survival while offering a surprisingly hopeful vision of humanity's future.
