Historical
From the New York Times-bestselling author of We Were the Lucky Ones, a propulsive and heart-wrenching story of a young woman entrusted with a boy’s life as WWII rages in Italy
1940, Italy. Lili and Esti have been best friends since they first met at university. When Esti’s son Theo is born, they become as close as sisters. While a war seethes across borders, life somehow goes on—until Germany invades Italy, and the friends suddenly find themselves in occupied territory.
Esti, older and fiercely self-assured, convinces Lili to join the resistance efforts. But when disaster strikes, a critically wounded Esti asks Lili to take a much bigger step: To go on the run with Theo. Protect him while Esti can’t.
Terrified to travel on her own, Lili sets out with Theo on a harrowing journey south toward Allied territory, braving Nazi-occupied villages and bombed-out cities, doing everything she can to keep the boy safe.
A remarkable tale of friendship, romance, motherhood, and survival, One Good Thing reminds us what is worth fighting for—and that love, even amidst a world in ruins, can triumph.
