From the author of The Widows of Champagne, and inspired by true events, comes a gripping and heartwrenching story of two very different women united to bring light to the darkest days of World War II.
 
London, 1933
 
At first glance, Austrian opera singer Elsa Mayer-Braun has little in common with the young English typist she encounters on tour. Yet she and Hattie Featherstone forge an instant connection—and strike a dangerous alliance. Using their friendship as a cover, they form a secret society with a daring goal: to rescue as many Jews as possible from Nazi persecution.
 
Though the war’s outbreak threatens Elsa and Hattie’s network, their efforts attract the covert attention of the British government, offering more opportunities to thwart the Germans. But Elsa’s growing fame as Hitler’s favorite opera singer, coupled with her secret Jewish ancestry, make her both a weapon and a target—until her future, too, hangs in the balance.
 
From the glamorous stages of Covent Garden and Salzburg to the horrors of Bergen-Belsen,  two ordinary women swept up by the tide of war discover an extraordinary friendship—and the courage to save countless lives.
