It is 1937, and Europe is on the brink of change. Kitty has escaped her family home in England to join an international brigade of fighters high up on the snow-covered Spanish borders, determined to lead an effective fight against the growing Fascist forces sweeping across Spain. In Oxford, Grace has embarked on a new posting, working with two medical scientists, one Australian, one a German refugee, on the brink of a great discovery that will impact a life-changing treatment for infection. But for now, they need to keep their findings away from the envious eyes of Nazi extremists. And in London, Lieselotte, one of the only surviving members of a German family rounded up by fanatics in their own country, is invited to a clandestine meeting, there to be recruited to work that will divert the course of international action. As the years pass and the bloody fighting in Europe bites, these women, bonded by idealism, love and extraordinary courage, leave an indelible mark on the historical landscape, united in their efforts to make change in a world riven by war.
