A brilliant sliding-doors reimagining of the passionate life of the first woman to win a Nobel Prize – and the life Marie Curie might have led if she had chosen love over science. Poland, 1891. Marie Curie (then Marya Sklodowska) was engaged to a budding mathematician, Kazimierz Zorawski. But when his mother insisted Marya was not good enough, he broke off the engagement. A heartbroken Marya left Poland for Paris to study chemistry and physics at the Sorbonne. Marie would go on to change the course of science forever and become the first woman to win a Nobel Prize. But what if Marie had made a different choice? What if she had stayed in Poland, married Kazimierz, and never attended the Sorbonne or discovered radium? What if Marie had chosen her first love and a life of domesticity, still ravenous for knowledge in Russian Poland where education for women was restricted, instead of studying science in Paris and meeting Pierre Curie? Seamlessly entwining the lives of Marya and Marie,Half Lifeis a powerful story of love and friendship, motherhood and sisterhood, fame and anonymity – and a woman destined to change the world.
