Knopf will publish Ian McEwan‘s new novel WHAT WE CAN KNOW on September 16, 2025. Jordan Pavlin, Knopf evp, publisher and editor in chief calls the book a “literary love story, a murder mystery” and says “the plot pivots on a legendary dinner party, and the recitation of a poem that is heard once and then lost for all time.” Rights were acquired from Georges Borchardt, with Knopf executive editor John Freeman editing.
