One Good Thing A Novel

1940, Emilia Romagna. Lili and Esti have been best friends since meeting at the University of Ferrara; when Esti's son Theo is born, they become as close as sisters. There is a war being fought across borders, and in Italy, Mussolini's Racial Laws have deemed Lili and Esti descendants of an 'inferior' Jewish race, but life somehow goes on-until Germany invades northern Italy, and the friends find themselves in occupied territory.
Esti, older and fiercely self-assured, convinces Lili to flee first to a villa in the countryside to help hide a group of young war orphans, then to a convent in Florence, where they pose as nuns and forge false identification papers for the Underground. When disaster strikes at the convent, 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 on an epic journey south toward Allied territory, through Nazi-occupied villages and bombed-out cities, doing everything she can to keep Theo safe.
