From the New York Times bestselling author of Room comes a stirring novel about a retired professor, whose life is thrown into chaos when he takes his grand-nephew to the French Riviera.

Noah Selvaggio is a retired chemistry professor and widower living on the Upper West Side, but born in the South of France. He is days away from his first visit back to Nice since he was a child, bringing with him a handful of puzzling photos he's discovered from his mother's wartime years. But he receives a call from social services: Noah is the closest available relative of an eleven-year-old great-nephew he's never met, who urgently needs someone to look after him. Out of a feeling of obligation, Noah agrees to take Michael along on his trip.

Much has changed in this famously charming seaside mecca, still haunted by memories of the Nazi occupation. The unlikely duo, suffering from jet lag and culture shock, bicker about everything from steak frites to screen time. But Noah gradually comes to appreciate the boy's truculent wit, and Michael's ease with tech and sharp eye help Noah unearth troubling details about their family's past. Both come to grasp the risks people in all eras have run for their loved ones, and find they are more akin than they knew.

Written with all the tenderness and psychological intensity that made Room an international bestseller, Akin is a funny, heart-wrenching tale of an old man and a boy, born two generations apart, who unpick their painful story and start to write a new one together.

"What begins as a larky story of unlikely male bonding turns into an off-center but far richer novel about the unheralded, imperfect heroism of two women." —New York Times​
