Ian McEwan’s latest novel, “What We Can Know,” is many things at once: It’s a science fiction imagining of a future world devastated by climate catastrophe; it’s a literary mystery about a scholar’s search for a long-lost poem; it’s a deep dive into complicated marriages; and it’s a meditation on how the past lingers and how history morphs with time.

“It’s the best thing McEwan has written in ages,” our critic Dwight Garner wrote in his review. “It’s a sophisticated entertainment of a high order.”

In this episode of the Book Review Book Club, the host MJ Franklin discusses “What We Can Know” with his colleagues Sarah Lyall (who profiled McEwan for the Book Review this year) and Leah Greenblatt. You can follow along, and add your own comments to the discussion here.
